Whenever I see pictures of my ex or their partner it gives me so much anxiety to the point where I'm shaking, the same happens when I come across old messages and I don't really understand why. I'm certain I'm over them, I don't want them back into my life and I don't really care that much about them but if I don't care why do they still make me feel ill? I know the advice I should follow which is don't go through their socials but sometimes I can't help it
