too much guilt

I'm a person who lives her life plagued by guilt that's a product of past failures; failures and disappointments caused to myself and others I care about. The failure to live up to my father's expectations of me, and my expectations of myself. The failure to make the people I care about happy, and proud of me. They say I have it all. And apparently I do. I should be happy and I should be satisfied. Yet there are so many things I blame myself for. For failing to achieve the best I think I can be. For failing to make my father proud of me. It's beyond stressful. And the worst thing being the fact that the stress is almost entirely self-imposed. I just feel as if I don't have the capacity to be someone great, or to do something great, contrary to what everyone says of me. They say I am talented in many aspects. Yet more often than not, I feel like a jill of all trades who can never be a master of anything. No matter how hard I try. Maybe it IS my mental block as what someone says of me. I need to be strong and move on. Get up when I fall. And just do the best I can, no matter how difficult things are and how many challenges I will face. I need to go on. If I believe. And most of all, I need to stop feeling the guilt. The guilt I have for being a bad owner to my 9 chihuahuas who ended up being given away, the guilt I have for giving Chu Chu away (those tears in her eyes), the guilt I have for not being able to be the best daughter I can be according to my dad's standards, the guilt I have for not being the talented dancer I want to be...everything. I need to throw away this guilt. Away from me.
