As an asexual who lived through ace discourse, I am grabbing you by the shoulders and coming as close to eye contact as I can and I am telling you; there is no shame in taking a break.
I know fellow asexuals where the only reason they are ALIVE is because they took a break from Tumblr when shit got bad and sure, people can wax poetic all they want about that being weak or selfish, but because those people took a break, they saw the end of this. The world did not lose an asexual that day because they listened to their brains, acknowledged their limits and their breaking points, and made that decision to take a step back. A human being lived, and that’s what matters. So look, I know it can seem selfish, it can seem self-centred, it can feel like abandoning your friends during this, but if you feel that it is what you need to do, take that break. Protect yourself. The world needs a living trans, intersex, or nonbinary person more than Tumblr needs another punching bag. You are not betraying anyone by refusing to martyr yourself, and the world is better with you in it than with you as a statistic. When it gets too much, take a break. Delete your account, if you think you should. Resurface under a new name years later if you do at all- if it means that you live, do it. There is no shame in having a sense of self-preservation. That is not weakness. In fact, I would call making that decision in order to protect yourself basically the textbook definition of strenth.
I would rather read your “archiving my blog” post than your obituary. The world is a better place with you above ground. There is no shame in taking a break when you need it and if anyone says otherwise, fuck them. You are more important than internet discourse. Do what you feel you need to do and keep yourself safe. Your life is important.
