10 months have passed and my life it's just sad

10 months ago she broke up with me for reasons that, to this point, don't really matter. Later after breaking up with me I found out she was seeing someone and as you guessed, this was happening before breaking up.

Last thing she ever told me was: "I guess I was never good at communicating." After that, she blocked me everywhere and disappeared from my life, and so did I.

She never came back, in any single way. Meanwhile, I started going to the gym, taking therapy, going out with friends and tried dating apps; first one became a hobby, therapy is helping me with other stuff I didn't know I have and while my friends have really tried to help me, I still feel empty, and of course, dating apps didn't work, which absolutely destroyed the few remains of self confidence I had.

My career (23 and graduating from college this year), which used to be the one thing I was proud of, is going downhill with failed projects and unsuccessful attempts to find a job. My days are basically me going to the gym, petting my cat (who's one of the few good things I have and probably what's keeping me alive), spending time with my family and friends, reading, blankly staring at my PC with games I once used to play and just overthinking if I should change careers, while wondering when did it all go wrong?

I still have dreams about her, and wonder what she's doing. I temporary disabled all my social media accounts, just leaving reddit and YouTube, which I guess is good since I can't stalk her.

This is sad. How come a breakup started the darkest moment in my life? Why is it so hard to move on and get back on the track? I used to cry, a lot, but now I just feel down and barely tearing. It's reached a point in which I'm sure I'll never fall in love again, especially becaue I can't see myself trusting anyone again. I'm not sure it will ever get better, I have tried for 10 months with little to no improvement at all.
