So... I've finally did it. I went to some psychiatrist because my depression was getting unbereable. Since I also suffer from debilitating anxiety, he prescribed me Lithium (so no antidepressants because my anxiety would be worse) and Lorazepam (to stop having night terrors and finally adjust my sleep schedule).

I've started taking my meds three days ago. Lorazepam works wonders; I am sleeping 8 hours and I do feel refreshed. But when is lithium going to kick in? I just want to stop thinking about death.

Does anyone here take lithium for depression?  Does it work? When will I feel normal again?  
I'm sorry if maybe my questions seem stupid, it's just that I'm tired of fighting. I just want to feel alright.
