I'm a 21 year old female who just recently got out of a toxic long term relationship.

Since the start of the relationship, I started noticing that i felt less and less confident. I've started wearing more coverage, ive been smiling less. I see my flaws way more than I used to. This might be TMI, but I don't even want to masturbate or have sex anymore because I feel so down on myself. This isnt me and I feel horrible all of the time.

Have you ever gone through this? What did you do to help build your confidence up?
