Congrats on the job! When I'm at work, I'm usually pretty focused on the work itself and not myself. As a cook during dinner hours, you may end up too busy to have time to think!
If you ever have trouble getting to work because of dysphoria, just keep in mind is that the job is what is going to get you the things you want to lessen it (ie, the hair removal example in your post). Anyhow, that's what keeps me going.
Congrats again, I'm sure you'll do good work.
