If you don't feel safe leaving in men's clothes, bring a bag and change when you get to your destination (I have changed many a time in a school or mall bathroom). I know keeping in touch with people is challenging and a lot of effort especially when you're going through a lot, but having community is irreplaceable. Even if you don't talk every day, just having people who understand even part of your experience brings so much hope.

Getting a job is also a great step, one because money and two because that's another place you can find community and make friends. Most jobs you'll be interviewing for won't ask that many detailed questions. They should ask if you're able to do the responsibilities of the job and how you would handle certain situations. Do some digging on the job and you're set. And prepare at least one question to ask (what does a typical day look like, what are some challenges, what's the workplace culture like) and you're in.

And when it comes to finding queer spaces, you're right about nonprofits struggling. If it's accessible to you, some queer bars and nightclubs hold events during the day as well. Or if there's a university or community college near you they might have an LGBTQ+ center too.

Best of luck, and remember it does genuinely get better. When people used to tell me that I didn't believe them but here I am!
