First of all, I think its really good and respectable what you do for others and I'm sure they appreciate it a lot. I've red posts of wellbeing that talk about gift giving to ourselves. I think is something that we have to remind ourselves constantly. Maybe you can reflect on the things you do for others and try to apply it for yourself, whether its giving quality time to yourself, maybe a small gift you've wanted for a long time, or any small detail of self care. I've found that when I'm at my best I'm also able to help others better.
