What about me?

This is a poor pitiful me post: please excuse me now..
If any of you know me well at all you might know that I have a tendancy to jump at any opportunity to take up for some one that I care about. Family, friends, you name it. (I know that this isn't always a good thing but sometimes it's hard to change who you are.) Let me give you an example: If my husband comes home from work a little agitated about something that some one had done or said to him; I would immedately jump on his side and be mad at that person for wronging my husband. (I know silly right) That is just who I am, I can't help it. It's like an animal instinct. I am a lot better about it now, I don't act on this instinct near as bad however it does still get the best of me from time to time.
I think I am just like my dad, but sometimes that is comforting. When you just need some one to get just as pissed as you about something. To validate your feeling and let you know that it's ok to be mad at that person, and some one to tell you that they would meet you in a dark alley and whoop the crap out of some one if they were ever given the chance. (Don't freak out here, my bark is bigger than my bite)
My husband and my mom and several other people I know think very objectivly. They are very good about pointing out things that I may not think of through my anger and most of the time that is very nice to have. Some one to walk you out of a cloudy head to see things the way they actually are not the way you some time think they apprear.
I have for years now joked that if I needed to call and vent and have some one agree that WHOEVER I am mad at is just a sorry SOB: I call my dad. If I need some one to tell me that I am being sorry SOB that should get over myself and stop being a baby I call my mom. hahah
Anyway, this instinct I have got the better of me this weekend. I took up for a family member that really didn't need me to do that. It slightly backfired and it ended up hurting me instead and causing some one close to me more problems than they aready were dealing with.
Some times I wish that this person would care more about me and my feelings but I guess this is the nature of the beast. I have got to learn that unless invited: my opinion and thoughts are mine and mine only. I don't always have to let everyone else know how I feel about stuff. I only know that I am a good person and I have good intentions no matter how they get misconstrude. I love my family and friends and I want to protect each and everyone of them from being hurt, let down, or wronged. I guess sometime I get a little big for my britches. Anyway- I am constanly learning things about myself and doing what I can to improve myself so this is just some thing I need to work on.
