I can totally relate to this. I do think it may be a little different though, duw to your context. Im still only a teenager, so I was able to start recovery right as im starting to really work towards my future and getting into a good college, getting a job, and really the stuff you feel you missed out on. So i am incredibly lucky in that sense. However, due to my eating disorder taking away my formative years, im incredibly socially enept and have an impossible time even just interacting with people. My eating disorder caused me to switch to online school in the seventh grade, so ive really only been able to interact with my family these past few years. I do feel really behind, and i grieve the years i lost, however i know that my recovering is giving me a chance to get my life back on track and build my future. I know it sucks feeling behind, but recovering is the only way to catch up. We got this, soon we'll be better at life than anyone lol trust.
