To be honest. I know how you feel. Its how I use to feel. Well about a week ago thats how I use to feel. I just started taking Zoloft and within a few days I noticed a huge difference.
I would strongly suggest going to see a doctor and seeing what can be done. Whether it is medication or a psychologist. Or what have you.
It completely sucks to have your mind take over your life. I have been going through this for prolly atlest 3 years of complete hell. I have lost who I am as a person. There is nothing that I can truly enjoy. But now, well. I have had 2 nights in a row where it tooks me seconds to fall asleep. I still wake up early but I am hoping that will change in time.
Things will get better, you just need to get some help. And now, do not wait, go see a doctor, even write down everything that you are feeling. No sense in hiding it all otherwise you wont get the right kind of help.
I hope this helps, even coming on here and talking about it all should help also.
I know it helps me at times.
We are here for you no matter what.
