Somewhere along the line people forgot to put themselves first. Or better yet, people have become divided and -in airplane speak- there are the people that only put on the other people's oxygen masks and the people who put on their oxygen mask, not realizing those around them need help. What the airplanes say to do is put on yours then help the person next to you. This is sage advice.
People exist in community. There is a balance to have for ones self. Often when speaking to individuals about self care I am told that those things are selfish. This may be true in one sense and extremely false in others. It is true going for a run, meditating, taking a hot shower, etc. could be viewed as selfish. On the other hand, caring for yourself will help you feel better and engage 'better' with those around you. So really caring for yourself is caring for those around you. For when you can't care for yourself, those around you may not be able to accept the care you give them with the same openness. It may feel insincere, burdensome, or have some other negative twinge.
So I urge you to figure out how to care for yourself, be selfish and take the time. Then when you're done don't forget to reengage those around you. Allow that gift of time and love you gave yourself to be felt and shared by others. It may not feel easy to take time for self care. You may not know where to start. That is ok. There is no right answer. You have to listen to yourself. Maybe start with one conscious deep breath and go from there. It is ok to be 'selfish' and engage in self care; for self care is a selfless act.
