Who have I become?

A year I go I was diagnosed with bpd, now I'm told it maybe cptsd, avpd and attachment disorder.

The thing is, I used to be so wild and just act on my impulses without I care in the world and I think people enjoyed my company because of it although it began to become apparent to me and everybody else that I had a mental health problem. Now its like I have become the complete opposite to my former self, I used to be the most outgoing person who would do anything and speak to anybody and now I cannot hold a conversation with a person, sometimes its anxiety but most of the time I don't know how to. I spend most of my free time in my room instead of socialising and I just don't see the point in trying to be social.

I'm confused to what is actually wrong. Has the transition from one extreme to another been down to the same mental health problem but how it manifests itself has changed? Am I just growing up? Have I developed a new mental health problem?

I feel like I don't know who I am anymore but at the same time I feel like I'm figuring out who I am. Before I couldn't bear my own company, now I can't bear anybody else's.
