Not satisfied with life despite my accomplishments

A few months ago I was in a really bad place following a break up I lost a lot of people in my life and I tried to harm myself a few times. Fast forward to now life is better I’m getting an apartment I’m going to college and my family life has never been better. I’m going to the gym Monday through Friday therapy three times a week but there’s something missing. The few friends I have are genuinely proud that I’ve come along way out of the dark hole I kept myself in but there’s something inside of me that’s sad. The people I did lose most of them I don’t care for I still do miss my ex, I feel unfulfilled. My next plan is to get a vehicle and work towards my masters but rn I’m in a state of just gym therapy home rinse repeat idk what to do rn with my life how what should I work on and how do I make myself better
