At a breaking point i guess?

i was baptized & confirmed lutheran. went to private schools all my life until last year..went off my medication for ADHD and i was battling severe mania..so everything has been screwed up for me for three years now. in a way, i guess i turned away from God. i no longer wanting to be recognized as a christian because so many people [especially on here] are so critical...they don't like psych medicine and how you should read the bible for guidance and he will heal you...that right there makes me turn against him. i'm freaking 18 years old and have to take two pills a day for the rest of my life, i read the bible enough, i have prayed...i'm not healed. why do they say this when you can't be healed? you're sinful. i'm sinful. no one can be healed.yes, i do know that in the old scriptures Jesus would heal people, but why can't their be a Jesus now? just don't understand anything anymore. point is...would any non-biased believer like to help me out?
