Losing Friends but not due to COVID

Sigh in the past 3 months alone, I've lost/grown apart of a couple of my friends. One of which I knew since 2003 and the other since 2016. We got together a lot during hangouts with 1-3 others relatively frequently pre COVID. It used to be almost every other week, but became less frequent to once every 3-5 months. Well with COVID I barely hear from these friends nowadays and they were not as clear about their needs to me as I would of liked. I wasn't able to change my own behavior in time for them to call the friendship off. Calling me toxic, but still wishing me the best.

Overall this is tough to deal with because I know I've been struggling real bad and as a result I've becomne a completely different person. Want to find my way back. I hope in a way that I can reunite with these people after COVID but I don't know......They have been affected by this too, maybe becoming a lot more intolerant for the littlest things, maybe they will be back to normal when things get better or maybe we are just growing apart and I need to find new people.

So hard to let go of the past when the future is so uncertain and I had my best memories back there with everyone.
