My daughter won't get out of bed for 2 days, She had a nervous breakdown last year and I fear history is repeating itself.

I'm sorry for the long post I'm just really worried about my daughter. I have a daughter(16) and a son (14) they're both good kids and no trouble at all. My daughter gets good grades at school and has a lovely small bunch of friends, she's always been a happy go lucky girl and nothing worries her. She had a small group of friends which I was happy about, I'm not a fan of big groups of kids at one house.<br><br>About 1 year ago, her best friend who was like a sister to her, left the country because her dad got a massive promotion and had to move. They would text everyday and call each other at least once a day, they'd still have sleepovers via facetime so they'd chat for hours during the night. <br><br>About 4 months ago, her friend was telling her how she's having a tough time adjusting, and how she misses her and the other girls and wants to come back home. My daughter was preparing herself for her friend to come back, and was excited to have her friend back. My daughter was talking about how they'd get ready together for their school dance and how they'd spend their summer holidays together.<br><br>Then out of the blue, my daughters friend said she couldn't wait any longer and booked a ticket to fly back to our country. My daughter was so excited and was looking forward to seeing her friend. They made plans to meet up and my daughter spent the whole day getting ready, she did her hair and makeup, she looked absolutely beautiful and I noticed how proud of herself she was looking. Her friend never showed up, she texted my daughter and said sorry, I'm not coming back, I was just saying it to make me feel better. My daughter was absolutely heartbroken, she cried so much and wouldn't leave her room, It was like she lost a part of her. <br><br>I tried my best to cheer her up, I took her out shopping, to get her nails done, everything just to cheer her up, but nothing did, she was always so miserable and unhappy. I got worried because she just wasn't herself anymore, I was afraid of history repeating itself because in summer 2022, my niece (29) had a massive breakdown and I saw the same symptoms in my daughter. My niece went through a nasty breakup and got depressed and had a mental breakdown. She wouldn't leave her bed for a month, she wouldn't take a shower or do anything, it was awful and I was worried it'd happen to my daughter. <br><br>I got her a therapist and she started going and seemed to be feeling much better. Some days she looked depressed but most of the days she looked like herself again. From the day her friend said she wasn't coming back, she completely stopped talking to her friend and they haven't spoken since.<br><br> Fast forward to 3 weeks ago, her friend posted on instagram with everyone a picture of her new hairstyle, It was the same hairstyle my daughter has. She looked very different and like a completely different person. My daughter saw that picture and she did go off on her on instagram, she said some horrible stuff, including how ugly she is and that shes copying her, I told her to take it down and not to stoop to her level, she apologized and took it down, but then I noticed she unfollowed her on everything, so obviously they're not friends anymore. <br><br>My daughter started seeming very depressed and sad, I noticed that she started wearing dark clothes, she'd wear dark eye makeup, she'd wear black lipstick, And she started listening to dark music, I worried because I saw signs of a nervous breakdown. Some days she seemed fine and happy, and other days she looked so miserable and unhappy. Some days she'd start fights with her brother out of no where and she wasn't eating well anymore.<br><br>About 5 days ago, we were all planning to go to the cinema as a family to watch a movie my son wanted and my daughter said she can't go with her face like this and she doesn't want to leave the house. It worried me because it was something my niece said when she wasn't leaving the house, she was afraid because of her appearance, even though there's nothing wrong with her. I told her I'd buy her a new makeup set and we can do her makeup nicely and buy her a new outfit and she said no I hate my face, I didn't want to make her go and I wasn't going to force her, so my husband and son went without us and I stayed home with her. <br><br>After they left, she went to her room and she's been there since, she's only come out once to use the bathroom and eat, she's been there for 2 whole days and I'm afraid she's having a breakdown, she won't get out of bed and I know if this goes on for long it'll be like what happened to my niece. I know I need to do something, but I don't know what to do. I just want my daughter to be happy again. What should I do?<br><br>TLDR: My daughter won't get out of bed for 2 days, She had a nervous breakdown last year and I fear history is repeating itself.<br><br>Edit: I got her a therapist when the incident first happened, and she stopped going after a few sessions, I've tried to get her to go back, but she doesn't want to, She assured me she's not depressed and she's fine, but I just noticed a lot of signs that she doesn't seem fine, She's been sleeping a lot through the day, and when she's up shes sitting and looking at the wall blankly, she's stopped keeping herself clean and has stopped eating, I'm just afraid because I've seen these signs before.
