Anxiety About Going Back to Work Post-op

I'm about 6wpo and feeling very fatigued and my vaginal cuff hasn't fully healed and I need another two weeks, but clear to resume other activities.

I received a call from work today to discuss if I can come back next week. My anxiety has been hitting me pretty hard since that call because I forgot to provide a form for my doctor to sign to give me more time because I am fatigued. And it's hitting me pretty hard that work is around the corner.

I'm looking for some useful tips to help with my anxiety other than the set clothes aside and wake up early to prep. If there are some perspectives that this community can lend to help me ease my transition back to work. I enjoy my job and my coworkers, however it can be stressful at times.
