Samtoo, here's an old song for you.
When I was just a bit younger than you, my first real relationship ended suddenly, after a wonderful year, when he got obsessed with someone else and dumped me. I was so hurt and sad and couldn't get over him at all. But then I used to play this song every morning, and sing along, even though it made tears stream down my face, and bit by bit, it worked it's magic, and I stopped hurting, even though I still missed him for years.
It might not be your kind of thing, but just in case.
Boz Scaggs - I'll Be Long Gone

In fact I used to play (and sing loudly to) the 2 albums Boz Scaggs, 1969 & My Time, 1972 (more upbeat, perks your body up, even if you still feel down) every day until they finally got me back on a more even keel. It took 2 or 3 months, but every day got easier. Home-grown cbt, I guess.
Kind of laid-back blues, country, jazzy, twangy mix. But it made me feel better when I didn't think anything ever would. I really couldn't get by without music.
I hope you get to feel better soon.
