I often get these types of feelings as well, and the others are definitely right in saying that if you need support we're all here for you.
If you have someone in your offline life that you can reach out to, you can always consider contacting them as well.
When I'm down I like to watch a lot of TV - mostly documentaries and Let's plays, but it all depends on the individual.
If you're feeling dysphoric, try something small that validifies your gender. I really hope you start doing better, and don't hesitate to reach out to me or one of the other members of Susan's if you need any additional support.
