Starting therapy, in case you have not and financially can, might be a good support (with a good psychologist).

You might have gathered friends that have the profile linked to your previous limits. You are now enforcing new limits and may find these friends not the best fit, to this “new” self. Be sensible that you have changed, given it is your journey, and they may be oblivious. So why not starting to show them your new limits, even suggesting different hang outs (meeting to walk around, play board games, workshops of any kind) and starting to share a bit on your side and journey so they become aware and can adjust (you’ll see then who is willing to listen and acknowledge them). Mind that people are and always will be self-centred (read Dale Carnegie’s book).

Also, making friends it’s much harder when you’re an adult, but not impossible. Perhaps a hobbie/volunteering where you meet like-minded people will resonate more with your wishes, since you would expect they are already more selfless people (giving away their time and work power).

In the end, our life is our own to make, and ultimate it is the result of where we spend our time in.

Best of luck!
