Does anyone ever feel they have lost their true identity? 

When I was a teen to my early 20s I was quite pleasant to be around, sometimes a bit of a bitch but normally I was a chilled and less morbid character. Once I hit around 25 everything changed, I was really depressed, I hated people near me and got irritated by them. I would flip put at any moment if something didn't sound right, I became really horrible. 

I was diagnosed with BPD when I was 26, I'm trying to learn how to control myself, as I have caused a lot of destruction towards the people I care about. But will I ever be the "same old me" again?
