Yes, it's not easy. It was far easier to sail along believing feminism had won, women were liberated, and the rainbow sparkles were all about love and letting people live their best lives.
The process of discovering what was really going on was highly upsetting and discouraging.
I won't like, it's been a glum, and pretty lonely couple of years. I find myself less trusting of people, so very disappointed by how easily people are/have been duped. And above all, so horrified and depressed by the realities of women's lives. When you actually look at the stats, it can be very difficult to process. So I agree with other posters - practise 'self care', do what you can in reasonably small steps, take breaks when you can. Be aware of when your own experiences make things harder, protect yourself against that.
I try to balance doing the difficult, combative stuff (letter writing, consultations, engaging with people who disagree) with things like helping other women - offering support, spreading news, donating, etc. I can only do very tiny things, but bit by bit and combined, we have already achieved a lot. There are thousands of women waking up to this, now. Our numbers only grow.
I also like to zoom out and look at a historical overview. Think of how much has been achieved in the past hundred years, know that all of those gains were hard won by hundreds of tiny acts of bravery (sometimes by acts of huge bravery, of course). This shit has been going on for a very long time. It's our work to continue.
