should I stay on the path I'm on or move home?

I (f25) have been living abroad in europe for the past 2 years. It started out as a gap year adventure between undergrad and grad school, and I ended up finding a job here where I worked/traveled and it ended up being an amazing year. I made some amazing memories, friends, and met my current partner there. It was one of the best years of my life.

I moved to a different european city and life hit me a bit harder this year. I started grad school online, work part time, have an internship, and am financially struggling here. I am doing long distance with my partner and often feel lonely. My parents are emotionally abusive and even though they live far from me now, they will randomly call and say things about how I'm "messing up my life" my living abroad and things like that.

I am happy to be here and feel like its easy to be healthy here, like besides having a ton of work to do my quality of life here is definitely high. I guess doubt just creeps in when I think I could be making more money back in the US, or that I'm missing out on things back home, or even start to think what will happen with my partner and how we're going to close the gap. Sometimes I wonder if its just my parents who've put any kind of doubt in my head

I know only I can decide if I'm on the right path, but how can you tell when you're moving in the right direction?
