It's easy to get hung up on not being good enough and end up feeling alone. There are
so many people who battle this same feeling for completely non-trans related reasons. Heck, it even happens because of the weather (have you ever read about
S.A.D.?)
The quicker you can divert that energy into something good, the better it will be for your own peace of mind. You could put it into anything... your job, or maybe a hobby, or art. There needn't be much thinking about what to do, just put it into action using those negative emotions to your benefit. The term in psychology is called
Sublimation. To some degree, everyone sublimates as we conquer challenges or get through hard times- and we grow. You could channel it into a direct solution, activity, or even by giving acts (but maybe stay away from that one for a little while). Sometimes we can spontaneously channel the emotion and bypass the bad feeling altogether, and that is true sublimation. It's one of the most useful things I ever learned about, and I hope it can be of use to you too.
Seriously though (as silly as this may sound), make sure it's not because of the weather. I've definitely been having to adjust to it, and several of my roommates are kinda down, too, at the moment. Nobody seems to believe me that it could be weather related. It's a real thing!
