I constantly think about the past. My life isn't terrible right now by any stretch of the imagination, but I just kind of wish I had what I once had. For example I wish I can go back to 2016-2018 because I miss my old job and the people. I feel it's really affecting my mental health. I can't focus, and I constantly feel depressed because of stupid stuff like this. I know that nothing lasts forever and I should move on, but I can't help but feeling this way. How do you move past this?
