what is wrong with me.I feel like i am going to exspoled. My nerves are off the chart.Family issues,me being sick with problem that has landing me on disability,anexity is terrible,I cant stop thinking about everything, like i cant turn my brain off.I am not sleeping if do only around three hours at most. i eat everything in sight one day then dont eat for two to three day which is causing problems with stomach.I cant focus on nothing.Thats why i say I feel like I am going to exspode. i by no means want to hurt myself or any body else.I just got so much on me and I keep everything inside.I cant talk to no one they just say relax it get better
