Developed anxiety and insomnia AFTER residency??

So I graduated a few months ago, and while a resident I really had no issues with sleep, anxiety, depression. But then the last 2-3 months of residency I started to randomly feel panic, get flushed, and uncomfortable in situations I used to be chill in.

Then I started waking around 3-4am and not falling back asleep about 2 months ago. And now I’ve progressed to low key having a few full panic attacks and not going entire nights not sleeping even a single minute.

Decided I probably need meds, got some lexapro, but haven’t started it yet since I’m currently on my first attending shift week and don’t wanna feel to weird.

Did this happen to anybody else?? What did you do to help? Will I ever be a normal human again?? SOS
