Others don’t notice my anxiety and think I’m a confident person. My own experience is different than what I project.

I have quite low self esteem and dislike having to socialise because I feel like I’ve said stupid things in conversation or acted weird. I’ll then beat myself up about it afterwards for the rest of the day or longer. 

I also suffer from anxiety headaches and stomach aches when it comes to my job. If we have presentations at work I make sure to sit at the back because if someone is sat behind me I feel as though my head is shaking from my body. I will then spend about 70% presentation trying to stay calm by shifting around the way I’ve crossed my legs or pinching my arm or chewing the shit out of the inside of my mouth. 

These are all things I’ve coped with this far in life. When I write them out they don’t seem that normal but I know others have it worse. I’m also good at detecting when others are anxious so I can see others around me get on with it as well. 

Are these the usual kinds of anxiety that others get or should I try to seek some ways to manage it?
