Welcome to the forum!
It absolutely can get better. And it is so normal to feel sad and lonely and lost. That’s what brought me here 
Learning to accept myself as I am has been a long and sometimes painful journey for me. Lots of mental health stuff came up after I’d stopped drinking long enough to really feel my feelings. But things do change and for me being free from binges and the chaos that alcohol brought to my life has helped with that.
This forum has been a huge part of my process. Just reading around and seeing so many people going through similar things, even if their lives looked quite different to mine on the surface, made me feel less alone. I’ve done yoga, meditation, walking and things like that to help connect me with myself. I have found an antidepressant that works for me, done CBT and am starting to address some vitamin deficiencies that have been impacting my health.
I went to Recovery Dharma (Buddhist inspired recovery programme) meetings for a bit after a couple of years sober but the structure etc wasn’t for me. When I first stopped drinking this forum was my sober network. Loads of useful info and resources. Find what works for you… Take what you need and leave the rest!
