No reason to ever feel guilty when you are doing self-care. You are entitled to your space & your time whether they like it or not.
I have a friend I have kinda distanced from with all the care for my animals that is needed now. She constantly needed outside validation that others weren't mad at her when we weren't the one calling her. Not my job to take care of those needs. I haven't had time to call for a few months because when I am done taking care of my fur baby family including my horse I am exhausted & really don't feel like talking on the phone. Absolutely NO guilty feeling cause I am doing what I need to to to take care of me first so I can function in my own life. We have to do what we have to do for our own well being & that has to be our priority. Just like oxygen on the plane. If we don't use it first we are no good to be there for anyone else needing us
