How Do I Become Confident Again Please?

I've generally always been a confident person. I dated this guy who basically treated me like crap, and straight after him, dated another guy who just destroyed my confidence. Like he put me down all the time, about everything.

I know that was stupid, I was going through a phase...

I've absolutely lost my confidence and myself. It's the worst experience I've ever had and I've been fighting to recover for the like, 2 months.
Any advice?
I miss my old self :(
