New to anxiety. Please read, I feel so lost. :(

First of all, thank you so much for reading. I'll try to make this as short as I can. This past August, I moved from Chicago where I spent my entire life living, to California with my then boyfriend because he got a job offer with an animation studio. Without hesitation or question about it, I went with him. We had been dating for 5 years, and I knew that I would be spending my life with him, so it was logical. However, neither of us have any family in California, everyone is back in Chicago. I was not done with college yet however. I am 2 classes away from earning my Associates degree. But, I found out that the school I was attending would allow me to finish my classes online, so that wasn't a problem. We were both super excited to move. I'm 25 and he's 23, so it was that time that we moved out of our parents homes and started our lives together. Everything was fine until recently, when everything has just seemed to be a mess. In November, my boyfriend proposed, which was one of the happiest times of my life. But it just seems like since that happened, my anxiety has gone crazy. I recently started to develop health anxiety, which is a whole different issue. I'm having an extremely difficult time finding a job out here, and it's making me crazy. I'm starting to look into colleges out here to get my Bachelors, but it's all extremely overwhelming to me. Back at my school at home, I had a very good advisor that helped me figure everything out regarding school. Out here, that's a different issue. When we moved, I was so excited to be going all the way across the country and away from my family. Don't get me wrong. I love them to death and they mean the world to me, but I was 25, and it was just time to go out on my own. Recently though, I have started to miss them more than I ever thought possible. I'm sitting here crying right now because of how much I miss them. I'm so stressed out between trying to find a job, trying to find a school out here, missing my family, dealing with the reality of being a "grown up". It just sucks. I've got crazy anxiety going on right now, and I'm having a really hard time dealing with it. I've had massive headaches for a few days, and I'm guessing it's just from the stress and anxiety that I've been dealing with. I love my fiance, and I moved to California so he could have his dream job. And I originally didn't have a problem with it. But now I'm having second thoughts, and there's really nothing I can do about it. Animation jobs are pretty much based in California, so I'm pretty much stuck here. I just miss my family, and sometimes, like right now, I wish I could pick up and move back home. Idk what I'm looking for here. I guess just some advice, or anything that might help calm me.
