Happy new year guys!

So just looking for some advice please :)

I am 27 and recently got diagnosed with BPD and my diagnosis has really helped me move on and enjoy life more because I now know the correct coping mechanisms and I feel more validated etc etc but I can't stop thinking about all the time I have 'wasted' not caring, ruining relationships, opportunities and jobs. I am ready to move on and start fresh and started actually acting on the hobbies that I want to do.

For example one of my best friends lives in Australia and I'm applying for a working holiday visa but it's only for below 30 year olds. I'm not quite there yet but I'm thinking what if there's other things I haven't done yet because I need to cram it into the last few years of my 20s? Also, my boyfriend has done, seen and travelled to a lot more places than me which I love about him bit I always get a ping of jealousy because these are the things I've wanted to be doing but I've been too busy overspending and engaging in reckless behaviour to actually get myself motivated to do these things. 

I know this is irrational and I can't change the past but I can't stop it from making me feel down and I just want to press on and do what I want with my life.

I hope this makes sense, I'm pretty high so apologies if this doesn't come out right...

Have a great day everyone!
