Not really sure of a good way to phrase the question in one sentence. Basically, I'm wondering if you had a number of good friends, an ex, and happy memories in a place, if coming back without those things makes it worse than being somewhere else entirely.
I'm not looking for any kind of sympathy, just would like to hear if this could be part of the problem. I'm back in San Antonio where I have a lot of memories (that were really good) and the people that made those memories are out of my life entirely. I'm realizing that I feel pretty depressed on average 2 or 3 days a week and I wonder if being back here isn't helping. I had one ex here who I was very, very close to as a friend for a long time. Took me a few years but I finally moved on romantically and then we were good friends for another couple years. Then she broke every promise that she made to me as a friend and it's hit me really hard. She introduced me to Ayn Rand, taught me the importance of keeping promises, and was able to think at a big picture scale just as big as mine. So for her to break her promises really shattered a core pillar in my life, thinking that surely she'd always keep hers after lecturing me so sternly about keeping mine.
I'm going to the same grocery stores I used to go to, the same apartment building, this time all alone. And I know that is for the best but I wish I could shake it entirely.
Maybe when my lease is up I should go some place where I don't have any such memories. Or maybe it wouldn't make any difference at all. Maybe I'm needlessly running uphill, or maybe I'll have this problem anywhere and I just need to face it.
