I am just getting back to work after being on medical leave for about 7 months

I pushed my doctor to allow me to go back to work part time at least. Now I am thinking it might have been a mistake

I tend to not be able to say no and part time hours have blurred into full time hours without me know. Workaholic part just takes over and I cannot seem to leave anything unfinished

Only problem is teen part wants time to play music, take photos, etc and is angry that I am back at work. Which causes binge eating and other self harm.

Just tired of battling and then I am not able to function at all
