How do I stop being angry im suck like this?

I'm becoming bitter and resentful of able bodied people getting to do thing i dream of and when my able bodied friends talk abt their issues I have been feeling angry with them for "wasting the mobility" I do physio and it's not helping much im bedbound while figuring out how to get the proper mobility aid.

How do i stop hating people for being able-bodied?
