Anyone here have a shit life for many years but is now much better? Do you find it hard to get over

For me I had a shit social life for most of my life due to depression and social anxiety, and still do to some degree but it's a bit better. But one thing that keeps me depressed though is that I can't stop thinking about all the years I wasted feeling lonely and depressed while other people my age were having an active social life.

I wonder, if I have a good social life in the near future, will I be able to stop thinking about all those years that I missed out on? Maybe it will be easy to forget about when I'm actually feeling content with how things are in the present?

One thing that makes it hard is that I don't think I can simply make up for those lost years because I feel too old now to do some of the things now that I missed out on. For instance, being sociable in your 20s often involves a lot of partying for most people, but now my hangovers are awful so I want to avoid that. It also often involves being in tight knit groups which is harder to find when you are older, because it's generally just harder to make friends when a lot of people are focusing on their family and have established friend groups.

BTW I know it's pointless to think about the past but it's hard not to. I think meditation helps, as does exercise and generally being healthy. I will be getting therapy soon for this too.)

Has anyone else been in the same situation before, and did you get over it once life got better for you?
