I had the same surgery as you and 2 years out I'm very functional.My speech is not as good because I had almost all of my tongue removed. I just ran 3 miles on my lunch break

I even do handstands in yoga class now - working on head stands...the scar on my forearm has really faded A LOT this past year- I was Ok with how it looked last summer but now its almost the same color as the rest of my arm skin (same with the scars on my chin and neck.)so this is exciting. I have come to like my scar there... - its a badge of honor for what I went through. Also it helps for me and everyone I meet who notices it to remember what an ordeal I went through and how much to appreciate my good health and recovery I was 33 when diagnosed. So I know how tough it is these first few months are. It sucks!
Wishing you a speedy recovery.
Thinking of you! K
