Identity and Social Media Within Recovery

It's been nearly ten years since I recovered from my past eating disorder.
This fact hit me the other day and I must admit, it made me very proud of myself. Proud of the work I did in that time of my life to better my future. It's strange; I feel so far removed from that part of my life, and feel like I am a completely different person looking back on that experience. My life is far beyond what I imagined was possible when I was 18, and my past self would be amazed at where I am today; not because of anything specific I've done that has been truly incredible, more so that I'm a functioning, independent adult who enjoys life and has ambitions. Yet that time of my life was a huge part of my developmental years and it would be unreasonable to completely dismiss it, as it is a part of my identity.
