Hello I can relate to you right now.
I have the strange dream like thing also, alot of staring and losing consentration. I wouldnt get too bogged down with what it actually is, its just your brain in overload. (I have been bogged down this week with trying to find out what it was but the answers just made it more scary)
You like me are early 20's. Your thinking ***** I am early 20's! Why am I not doing loads of crazy stuff! Why can I not be better ect......
All this talk is not helpful, you like me have had problems in the past and like me you are undergoing stress and change. I think its fairly normal especially for people in our age range.
In time you will accept help, and accept you need a bit of help. Once you have done that you can begin to move forward. I think I began doing that last night. Its a nice feeling. Take something from the anxiety/depression. Change something in your life for the best.
Me I am not taking drugs ever again and I quit smoking. Its time to appreciate life for what it is. We will get there, it makes us stronger!
Sorry if this makes no sense, I am actually half talking to myself.
