You can't do anything positive in your life if you are around someone who makes you feel bad for good things that happen. Many times, guilt like this is created and fostered in childhood with your family of origin. Others put expectations on you, and become resentful of things that happen for you (and not for them). We take that in and end up feeling bad for things we should feel good about.

There is NO REASON for you to feel badly about positive things that happen in your life. If you world to get/receive/achieve something—it's yours. Nothing is stopping them from getting what they want... and it's not your job to caretake others through your successes.
