Feeling overwhelmed in the workplace

[user98700981]

For the past year i have been struggling with feeling overwhelmed in the workplace in noisy situations. If there are a lot of people having a conversation I can't focus and my head feels as if it's going to explode with everything going on. I start to feel panicky.
I work in retail and try and do most of the jobs out the back away from customers/colleagues but its getting busy now that i have no choice but to be around them.
I shielded for 14 months and have only felt like this since then, I can't believe that one year later I am still struggling. I use to be sociable.
I have a new manager who joined 6 weeks ago and I'm worried she thinks I am rude/unfriendly for been like this 😢

I think lots of people have been affected by lockdown and are struggling. I'm sure you're not the only person.

Any tips on how to deal with these feelings? I am trying not to avoid the situations that make me anxious but sometimes its just too much to cope with.
