<human>: So, pretty much what it says on the tin. 

I'm a late bloomer in the dating game. First everything was when I was 20 years old, with this guy who had some pretty big mental health issues at the time (and possibly still does -- been NC for a while) and had issues getting over his ex girlfriend who had dumped him 6 months prior to us meeting. 

I've always had low self-esteem, and would go on to be diagnosed with persistent depressive disorder when I was 22. I started to compare myself to this mysterious ex, exacerbating my already poor sense of self-worth, to the point where I thought absolutely *everything* about me was flawed. 

Since then I went into therapy, got on medication, moved across the country and have met another guy who is great. I feel like I can be myself around him and we hit it off pretty much from the first time we met. However, I am doing the same comparing myself to the exes, amplified somewhat this time around by the fact that this was a longer relationship, and he is still involved with the social circle his ex is a part of. Every time I think about how he might have been happy with her, I get pretty sad and just want to curl up into a ball. It's hard to articulate. 

Has anyone else had to deal with low self-esteem and comparing themselves to others? I should add that I have never met these exes in person, and my current partner is NC with his ex, so I am not insecure about cheating. Just how to love myself for me.

Condense the text into a few key points
<bot>: Self-imposed Scott Pilgrim vs. The League of Evil Exes scenario is really unhealthy for my self-esteem. Need help learning how to live and let go and accept myself.
