Please get help. Seriously. I know it's hard when it doesn't seem like it's helped before. And I'm not saying God won't answer prayers because He will and does... But you need professional help. Yes, the medication can cause suicidal ideation, but that doesn't mean they always will. Therapy and therapeutic techniques do help. So do meds. Please, please, seek help. There's only so much we can do to help you through the internet, and there's only so much prayer can do. God can do all things, the impossible, but with mental illness, we often need to treat it with the work of professionals. Please trust that God has given these people the ability to help you.
EDIT: Just thought of
this article and thought it applies, so I'm going to share it.
