recent on going

My parents split up over a year and a half ago and my dad sends abusive messages to my mum still who works hard and doesnt deserve it and blames everything on her. Ive been with my girlfriend for over half a year but get jealous when guys who dont know shes taken hit on her but i dont want to step in because she wont try it on with them but i always question her, and i find it hard to trust her since we broke up for a week in the summer over her parents finding out about us having sex and her beeing grounded for a month. My girlfriend used to self harm and i get scared she will do it again because its addicvtive, and she wants to try weed, she can be trouble but shes worth it, im crazy about her but she drives me crazy, and it stresses me out and i take it out on other people, i almost lost 2 best friends this week, i know i have something wrong with me because im so angry and depressed and cant get sad thoughts out of my head. help me please

Dear Thom16, is there counseling available at your school or in your community? I recommend you seek professional help and talk with a family doctor about your depression. It sounds like you are still grieving the divorce of your parents. Though it is good that your parents are apart since your father is abusive - it is still a loss and still very stressful.

It's very difficult to maintain a healthy relationship with a girlfriend when you are dealing with your own issues and she is dealing with hers.

I talk about managing anger in relationships, abuse, the connection between anger and trust and more. *Link removed by mod*. God bless!
