This might sound like it's entirely out of the realm of possibility for a lot of folks, especially depending on where you're located. But being in community with other transmasc people in person, having one on one conversations with people who honestly and truly understand you in a way that most other beings won't? That's life-affirming. That's life-saving. I had no idea how alone and broken I felt until I was staring at someone who was undeniably whole and wanted saying those same words back at me about themselves, who was living a life so similar to my own and yet felt so remarkably lonesome.
If in-person community is not viable or safe (for disability reasons, physical safety reasons, financial reasons, any other reason), finding virtual support can be just as valuable. There are discord servers, there are Facebook groups (if you're an older person like I am and still use Facebook, anyway). I promise you, there are places where your presence is wanted, even if they don't know it yet. Even if you don't know it, either.
The closet can be safer, but that doesn't stop it from being treacherously lonely at the same time. Finding an online community can be like having a small piece of Narnia to escape to as we sit amongst the mothballs and the dust spending their days in the closet with us.
