Wasted it on a scumbag, but this is a new year now, so onwards and upwards.
No point dwelling on what ifs, that's how you get stuck in cycles in the first place and then it becomes a self fulfilling prophecy, and you'll never get out of that mindset, just around, around, and around constantly, and you'll get stuck deeper and deeper into it. Been there, unfortunately.
Been there myself, but I've helped myself to change my mindset, and after a long time, I have, and I'm in a better place now. It takes a lot of time, effort and hard work, but it can be done. I never thought I'd recover from all this horrific trauma, but I've done so well recently. Learn to help yourself, be there for yourself, to rely on yourself and no one else. Only you can be there for you 24/7, no one else.
Hope things ease for you
