Start by caring about yourself

Don't let others guilt you or make you feel bad for putting yourself first.
Self-sufficiency and sustainability are essential to your survival, and it's also the only way you can be of any value to anyone else. I know many people who live the lives of martyrs, finding significance in all the sacrifices they make for others, but that can't last forever and breeds a lot of self-pity. I'm not telling y'all to throw your middle fingers up at the world and isolate yourself. I'm asking you to remember that your energy to be a part of this world comes from self-care and giving a damn about what matters to you first. In a world of absolutes, this may sound selfish, but it's not. It's not selfish to put yourself first, it's selfish for others to expect you to put them first. Handle yours, and let that show others to do the same for themselves. Then, and only then, will you have the energy, enthusiasm, time and love to be there for others who really need you.
