Sometimes going outside and being in nature helps me. I try to notice the sights and sounds around me, and feel the fresh air and sunshine. The more I'm in my house, alone, the easier it is for me to get lost in my head.
I agree with what someone else said about support groups too. It used to be SO HARD for me to force myself to go, but now I go, listen to other people, share a little, and feel better for connecting with people.
It's so easy and so tempting to stay home and isolate. The pull is so strong sometimes. But posting on here is a start!! Maybe a walk around the neighborhood for some fresh air and to clear your head??
