I'm confident in myself, I don't think I have low self esteem and I find it easy talking to people, but after every social interaction I just feel like I've embarrassed myself. I'm afraid of everything, I'm scared to go outside in case I get sick, I'm too scared to get into a car because I start imagining how I could die, I'm too afraid to go to new places in case I do something wrong.. I second guess myself all the time, it could be something simple like 'oh no should I have put that in the microwave?' or 'am I supposed to boil potatoes like this?', even simple maths I can't do because my brain makes it a big deal like 'are you sure that's the right answer?'. 

My s/o is getting sick of it too.. because I don't want to go anywhere out of fear. I'm even too afraid to eat at a restaurant because I know I'll feel embarrassed saying something off of the menu wrong. He wanted to show me off to his work colleagues but I let him down because I was too afraid, and I really upset him.

I don't know why I feel like this, I'm very health conscious and I look after myself but mostly out of a fear of getting sick. Any slight imperfection with my health scares me, even a cavity. I've been putting off seeing a doctor for years, and I'm afraid of taking medication even if it'll help. 

Just venting.. thanks if you're still here
