Getting it *is* a little difficult, and I've been in the LBS position.
1) Disconnect yourself from your W's alleged evaluation of you. You feel rejected because SHE rejected you. You feel discarded because you think SHE discarded you. Stop that!
2) If you have C, ask your C very directly to help you with this. I spent a year and a half in weekly therapy. Do the work.
3) Mind your health and appearance, and GAL. These things really help.
4) Seek out the good in yourself and revel in it. Examine it. Appreciate it. Claim it and own it.
The trouble with having an open mind is that people put things in it.
