Admit it, expressing yourself isn't your real goal. You're reacting to a bad news story and you want other internet strangers to validate your feelings with affirming replies and karma so you can feel satisfied for all of 10 seconds before feeling angry and/or emotionally empty again. Believe me, I've been there. It's not a fun cycle, and Reddit is profiting off of your misery over and over again.

The only way to break out of this cycle is to take action, either political or personal. Make a list of things to do and people to contact to make doing those things easier. Set deadlines for doing those things, and tell others those deadlines so that they'll stick. For example, you will personally meet face-to-face with three different policymakers to express your displeasure and demand they tell you what they intend to do about it, and/or you will start a bank account for yourself or a loved one specifically for the purpose of transporting them to an abortion-friendly state if the need arises, making sure to have at least $3000 in the account by (arbitrarily) July 15.

I know this isn't very feelings-validating-y, and that it's not really meeting the expectation of Maslow's "sense of belonging" stage that people seem to be using political subreddits to obtain, but doing these things will make us more emotionally healthy and productive in the long run. Trust me on this, please.
