You should take a look in the Inner Game section...
Get some new beliefs sorted out, and such.
There's probably a good reason you used to believe these things before, but we both can believe that they were not helping you anymore.
Break the spell.
Leave them behind, you no longer have any use for those beliefs that used to hold you back...
And for good measure, sit down and find a few to replace those beliefs, and make sure that these new beliefs are truly helpful for the situation you are now in.
hehe
And I mean that, sit down and write out positive beliefs.
And write them in the positive. e.g. "I believe people are basically good, and have no cruel intentions" or something in that direction.
Then re-read these new beliefs once a day, and "fake it til you make it".
Persistence is the key to changing beliefs (It's not enough to think once that you don't want to believe a thing anymore, you have to prove to your mind that you really want this new belief instead of the old)
