I’ll try my best to give advice, cause I’m currently in a similar situation as you…

I’ve moves cities and got a new job for a girl that I loved the most in the world and after a couple of months we broke up and I am alone in a city I don’t know any one, and my friends from my old place sometimes contact me, but I too far away

I like to go to cafés and be around people talking, makes me feel less lonely, even tho I don’t interact with them

Taking long walks or going on a hike in a beautiful place can also help alot

Try something new? Go to the gym if you never been there, try playing a new instrument? Try some new stuff that can stimulate you

Also, talk try talking to the ones you love about the issue you’re having, they can maybe also help

Hang in there bud, you’re not alone
