I know this is going to sound really stupid, because it did to me at the time, lol.
My therapist told me to hug myself whenever I needed a hug. Literally wrap my arms around myself and comfort me. (see, I told you it would sound stupid!)
Did it fill the need to be hugged by someone who loved me? Nope. But, slowly I realized that being hugged by my husband didn't fill that need either. And through the process, even though it felt ridiculous to me, I learned to love myself. I learned that I can depend on me, and count on me when things get rough. And even though it feels silly, I still do it sometimes, just to remind me that I am here for me.
I much prefer a hug from my children or my new BF, but I don't need those to get through life. I can give myself what I need in a pinch now. Crazy, but true.
