So sorry your son is going through something so hard. I think I did something similar with my first major relationship where I poured most of my energy into the relationship so when I ended it, I realized that I didn't really live near any of my real friends and moved so I could just start over. I think a lot of young people make that mistake (and some older people, too!) It's really hard, but maybe you could encourage him to find some creative outlets to focus on developing himself a while? Anyway, hope you are feeling better enough to take walks or other things that get all that stress out! Big hugs!!!
