I would start feeling insecure when i felt happy... still do, sometimes!

But you are ALLOWED to feel happy!
hmmm. Anything we can do to help you feel stronger and more centered these days? Sometimes i find that knowing what i stand for helps me to feel more centered and less upset when things happen. For example, I know that when i receive criticism, i want to stop and consider if its being said in a helpful way or an angry way first, before accepting that its true and letting it get to me. I don't always succeed, but knowing what i want to do ahead of time, helps.
My friend Rose uses humor to help sheild herself from feeling hurtful criticism.

If you crack a joke... even if you just keep it to yourself, it helps deflect the criticism!
