Hi Jack,
Reading through your journal really resonated with me, so first, thank you for sharing. I feel you in your struggle in questioning what your sexual preference is. My mind also doing something similar to me, making me question so many memories, but it is just the addiction fighting back. And it's fighting back with bullshit, because the addiction has nothing to truly hit us with other than shame. And the mind can even confabulate shame. I try to laugh the thoughts away, or even hit it with logic. Attraction is something we generally know. Even those who try to suppress it, they catch themselves throughout the day feeling an attraction. I'm sure it's no coincidence that you're having these thoughts as you're quitting an addiction.
I also really empathize with your struggle with being stuck because of covid. I too feel this. Stuck in the house, limited options to go out. I try to plan things as best I can. Play a game, go for a drive, go for a walk, call a friend, focus on work if I can. It does offer a little reprieve. Watching movies and TV may also work, but it hasn't worked for me, as my mind isn't occupied enough, but could work for you.
But you've made some pretty nice stretches, so you're making progress regardless. Your posts indicate it. We're all just trying to feel our way through this thing. You're doing the right things for yourself! Stay stong!
