Who else gets jealous when you see a couple being happy?

I get jealous when I see couples being happy. I feel jealous because I’ve never had a partner, no matter how hard I tried. I’m 21 now and I’m still a virgin. Never had a gf, never been to a party or a club, just vegging around and trying to survive. I come to Chambers to see people who are my age are in a successful relationship, having fun with their partners, or sharing their amazing experiences with people they love. I feel so sorry for myself. I don’t want to be lonely anymore. I want someone to love me. I’m tired to be alone. Shit, I’m even jealous when I see a happy couple in movies. I just never had love.
