I hold on to the good feelings, or at least I try to, by starting threads in this forum, by emailing my T the same night or next morning about my session, and sometimes by emailing about my session to a couple friends who know about my therapy. Sometimes I write a poem about my feelings. I also think about the nice things my T said, or what I said, before I go to sleep.
I don't know why the good feelings slip away so easily. I was told it may be a borderline trait. I tend to think the feelings aren't real if I don't keep thinking or talking about them, or at least emailing my T about them. It's kind of an obsession.
How can we create the good feelings for ourselves? My T thinks mindfulness, yoga, and meditation are the answers to that question. You meant good feelings in our RL, didn't you? Doing something pleasurable each day, and helping someone each day. I went to yoga class today, and I did feel those good feelings. Participating in activities you enjoy creates good feelings. Exercising does too. For me, walking by a lake and going into the water do that too, but I can't do that in the winter.
Thank you for this thread, rainbow_rose. I'm looking forward to hearing how others answer your questions.
