How do I regain life energy

My LO is a colleague on the same team. I dodged her for 2 months and was feeling better and healthier, training more etc..

Until one day, she came to me crying and I let her speak to me. We haven't spoken since then (its been a month and a half), but ive been feeling really bad, regressing, loosing muscle and life force.

All I want to do nowadays is lay in bed, not eat much. I took back to back vacation and sick leave to dodge her as much as possible but Im not sure if its even helping.

Ive seen psychotherapists, ive told them im depressed and they denied.

Does anyone have tips of breaking free at least physically? I feel so out of energy and everything I do is forced nowadays.

Maybe I should just quit the job to be able to reset, but again this 3 weeks distance I created with her doesn't seem to be working.

I will really appreciate any tips.
