I am scared all the time about everything. I have this constant fear of death, and i dont know what to do. I either think that i have some disease like cancer, or that someone is going to murder me. i dont know what to do anymore i cant stop being afraid. i have my number to someone a long time ago that i met on yahoo messenger who i didnt know, and i always worry it will come back to haunt me and something terrible will happen. i just dont know what to do. Am i losing my mind?
