I think the thing I'm most scared of is what I'm going to do with myself and how I'm going to spend my time. I'm single, no kids, live on my own, my parents gone, sisters live 4 states away from me. I moved here right when the pandemic started for my job and haven't made any friends. I mean, I have work friends but those are colleagues, not friends. I work, I stay home, I cook, look up recipes, make stuff, eat stuff, think about what to make/eat next.
I have no hobbies other than scrolling through my phone and watching a little TV, maybe take my dog for a walk. How did I get to be 53 and have absolutely NO hobbies? Okay, I like to read, there's a hobby. But I need new hobbies to occupy my time that is currently taken up by food, food and more food.
I'm not scared of the surgery, or the changes, I'm scared I will have too much time on my hands and nothing to fill it and that I'll fall back into my old habits. What in the world am I going to do with myself?
