I think interactions with my father makes me feel suicidal.
Why would he make you suicidal?
I love my father and he has done everything for me, but we can't always get along
You need some therapy with your dad. You shouldn't feel suicidal. If you do, get some therapy.
I still feel like killing myself.
Even if you are still hurting , I think it would be good for you to see someone or check yourself into the hospital. You can always work on your relationship with your father but you need to prioritize your mental health right now.
