Your not alone believe me, take a look at some of the messages on here, there are far more people feeling like this than you think... I was having really bad attacks of paranoia, hearing things in mmy head, i still am but my doctor thinks it was because of the tablets i was on.
You need to see your doctor try to tell him everything as he can help,i have but i havent told him everything i used to cut then i started again but im too embaressed to tell him so i will be telling my councellor tomorrow, I really do feel for what you are going through but you must get some help, even if things get worse you need to keep going because there are lots of meds and treatments that can be used.
What you have to try to remember is that this is an illness,and it will go away with the appropriate help.
I find that writing my thoughts down help a little bit to vent everything i carry my note book with me everywhere even to work and if i need to write i will.
As for the weight issue that is a symptom of what you are going through and nothing will help you with that untill youre feeling better.
I have had to stop takign meds for 2 weeks so i can take some new ones and its killing me im living in the hope that they will be better for me so thats keeping me hanging on.If you need time out take it, Im always arguing with myself because i dont know if im being rational or not which doesnt help but you can get better and get through this.
Get some help, and try to get through this.
My thoughts are with you ....starr
