Help please

I am so so so anxious, I cant even describe it. I have this horrific anxious feeling going through my body where it feels like im about to do something terrible. I feel incredibly sick, shakey, panicky. Due to this harm ocd episode. I am so scared that I might act on a disgusting horrific harm intrusive thought. I dont wanna be near knives, go to the kitchen or even get up. As im so scared that Im going to act on it. I know I dont want to but this anxiety and horrid feeling makes me feel like i do. I am petrified the anxiety is terrifying. I sat in the kitchen earlier while my brother was close and I was scared because it feels so real even typing this im starting to panic. Please respons please and please say if your uk based it brings me a bit of comofrt as I know im not alone in this country! What makes it worse is my family were talking about their aspirations and dreams then i felt even more scared of the intrusive thoughts because if i did act on them they would be destroyed and then I also feel so much guilt cos i get scared my bf is scared of me has anyone had this does it go.

I have the thought of what if I lose control and do something out of my control like scream for no reason or yelling in a store or just blurting stuff out that’s not in my control and it causes so much anxiety and causes me to feel weird. I always think I’m on the edge of losing control of myself and it’s exhausting living like this. Any tips?

6 months ago I had a severe panic attack and it’s changed my life. Scared of 99% of foods, can’t take meds out of fear, been hospitalized a few times cause of blood sugar drops and other health scares due to poor eating. I’m constantly scanning my body finding any little thing that’s uncomfortable and then fixate and panic over the smallest things. Whether be a smell I’m unfamiliar with, a weird sensation in my arm literally anything freaks me out….. who has had success with exposure or has dealt with similar issues. I feel like I’m unintentionally slowly killing myself but I’m too scared for meds and therapy doesn’t seem to make much of a dent right now. Please share some success stories I need hope.
