I think my son is on the verge of suicide

My son is 13 years old and I feel like he's not my happy little boy anymore. I think he's on the verge of committing suicide. I’ve had to go against my better judgment and take his phone for nearly a week and after I came back I found out that my baby is self harming and has plans to commit suicide. His post was in the comments of a suicidal post.<br><br>It’s been bright red flags against him for months, but I didn’t think it would get too worse this soon with bullying and getting a lot of hate messages. I felt so useless. I really thought he was a tough kid and I think I messed up. I found out he was being bullied for months and kept it from me. I just want my happy baby back.
