Just a place to have a vent if you want!

This could be a really terrible question, and i'm thinking there may be a bit of a mix of replies, or none at all! I got thinking today, accidentally, about the past 2 and a bit years since I began my treacherous journey through the waves of depression. Back then, everything was going so well - or so I thought..

I've gone from being in a happy relationship, to single - which I am more than ok with, that had to end.

I thought that I would NEVER see a Therapist, nor would I go on antidepressants. I'm now onto the second therapist, and 3rd failure of an antidepressant.

I have a beautiful dog now!

I have lost my passion for a job.

I'm living with a guy who I met on a support sight similar to this one - that one is a little strange!

I now am living with a chronic injury which likes to cause me constant pain.

I am completely changing career paths because of this injury

Moral of the story, if anyone had have told me that all this would happen, I never would have believed them. I never would have believed that this depression would last 2 years, let alone 6 months. Truth be told, all this could have happened regardless of me falling down into the depths. It is just really confronting looking back at it all.
Like, who am I? Is this still me? Was that really me? Can things get better now?
