I think it's hard to decide what is and isn't depression, especially for someone else... I totally get how you feel, though. I also think there's absolutely nothing wrong with trying to find happiness. For a very long time I felt like I had to be happy where I was. It's easy to think ''others are happy, so why aren't I?'' But it also makes no sense to think that way - we're all different.
And just to share my experience: I moved to a different city and started doing something I loved, and I even went to Paris. It was amazing and I'm so glad I did it. Doing all of that also made me realize that my problems weren't going away. I was depressed at home, and I was depressed in front of the Eiffel Tower. But it's still bloody beautiful. So maybe those things didn't fix me or cure my depression, but it was vital for me to know that I can travel anywhere, have any amount of money, that I could do what I loved, and I'd still have the same issues.
I think we forget that sometimes we need to learn those lessons by experiencing things. I really think we have no way of knowing unless we try things. Move to a city, move to the middle of nowhere, try a new career if you have the option, fall in love if you're so lucky, why not? You can always decide it's not for you.
Maybe zero of this resonates with you, but reading your post this Rilke quote came to mind and I just have to share it, please do ignore all of this if it doesn't resonate:
''Be patient toward all that is unsolved in your heart and try to love the questions themselves, like locked rooms and like books that are now written in a very foreign tongue. Do not now seek the answers, which cannot be given you because you would not be able to live them. And the point is, to live everything. Live the questions now. Perhaps you will then gradually, without noticing it, live along some distant day into the answer.''
