Hey girl3900!
I remember you and have actually often thought of you because I went through a phase recently of thoughts exactly like yours. I have been diagnosed with GAD with OCD traits. I just want you to know, OCD diagnosis or cause or not whatever, the simple fact that you fear these thoughts is all you need to know in terms of not acting on them. It doesn't matter whether they are OCD based or not. There is a world of difference between a true desire to act on these thoughts/images and what you are experiencing. You are not comforted by these thoughts and they scare you. I know it may be hard to believe, but you will get through this and you will not hurt yourself. And BTW, whether or not you think you have OCD, I think you have a mild form of it. Because Zoloft can cause anxiety at the beginning of using it, that anxiety can manifest itself in many ways, one being obsessive, scary thoughts. What I mean is if you are feeling anxious, maybe the way YOU express it (like me!!) is through obsessive, scary thinking. So I mean, I don't think the Zoloft caused the thoughts per se, but rather the anxiety... which then caused the thoughts. How long were you on Zoloft? Maybe it wasn't the right drug for you. I'm on Effexor XR, which helps me. I stay on a low dose though so I can face the thoughts through therapy, which also helps a lot. I'm a firm believer that meds alone are never enough. Also, another question if you don't mind, why were you on Zoloft in the first place?
Oh and about the awful feeling, I am altogether too familiar with it! I think it too is another form of anxiety, and maybe mild depression. I wake up with it almost everyday, but it usually fades. It something you have to work on getting rid of: with a pleasant activity, excersise, delicious food, anything positive to get your mind off it. We have a lot on common, girl3900! I hope you'll keep me posted! Take good care.
