You are not alone but I understand it feels that way right now. Please pause and press reset on yourself. You can only do so much, you are awesome but you are not a machine, you are a human being not a human doing.
SOME THINGS I DO TO RESET MY SELF WHEN ON SYSTEM OVERLOAD:
-I stop doing anything for as long as I need to, for my nervous system to calm down.
-I take a bath (I’m in one now actually ?) and focus on something I enjoy, something positive (hence me writing this post).
-I check in with myself and ask what do I need right now without judgement? Then I honor my needs. Whether it’s food, a nap, a cry, a healthy distraction, alone time, whatever.
