I'm currently playing the waiting game as well. I'm pre-t and in therapy edging ever closer to getting my referral letter, but have yet to find a doctor. I also don't pass at all, despite all of my attempts, which definitely adds to my dysphoria and bogs me down a lot of the time.
There isn't much I can do yet in regards to getting on T other than wait so I'm trying to spend that time being productive and staying positive/hopeful. I've started working out to try to lose feminine features (read: curves). I know it's a big part of why I don't pass. I've struggled to find motivation to do so for a long time, before realizing I'm trans, but I think the desire to have a lean, fit, masculine body is what's helping drive me now. I also know that T will only make it easier, so I look forward to that day.
If I'm having a bad day and I haven't done so already, I will shave (even though it's just peach fuzz) but the act itself makes me feel more "manly" and gives me the practice. If I'm able, I'll also go shopping for men's clothes because it strangely helps, even if I'm just browsing for stuff I can wear "someday."
I also try to get myself excited for therapy days each week because I know it means I'm one step closer to my goal.
I also like to watch FtM YouTubers. It helps me see where others have started and seeing their amazing transformations gives me hope and helps stave off feeling down. I always feel like, "someday I will be there and everything will be better."
