I think that sometimes your desire to sleep is caused by the fact that all this thinking and subconscious thoughts are tiring your out mentally, which causes you to just want to rest. :hug; I don't know much bout meds, but what i do know is that if you think that you can overcome your situation, then that definitely helps. No matter what situation you're in, you're even stronger than the challenge you're facing.
I think that sometimes its better to introduce other factors, such as calmness. Reading a good book, or writing a diary can help you express your thoughts as well as have an outlet for whatever feelings you're having.
i hope my advice helped. If you wanna rant, you know that i'm always here.
