Hey! I'm 6 months out from my surgery. I felt the same way early on, but a lot of what's in your head, you learn that it's only in your head. (Over time)
I was terrified of everything. Lifting things that are too heavy, eating anything, drinking alcohol, traveling, you name it.
6 months out and I now eat whatever I want (chewing like normal), I've traveled through Costa Rica, I drink alcohol with no issues, and I'm back at the gym deadlifting 250lbs. (and even working out my abs)
I never thought I would make it this far this soon, but that was just in my head. Of course, I didn't rush anything. I ate new things in small doses, I started at the gym with extremely small weights, etc., but over time you learn what you're capable of. If you ever think "oh, can I do this?" I say give it a shot and see what happens.
I stopped taking all pain medication 1 day after my surgery and haven't had even an Advil since. I had some weird fear that it would slow down my recovery process (as I learned in the hospital) so I ditched it.
I'm even going for two more surgeries. Next up, a loop ileostomy/pouch creation, then 5 months later, stoma removal. Can't wait to see where this takes me.
This is just my experience. I know everyone has a different reason for being where we are.
Good luck!
