Why do I let it get to me?

For the most part I have a I can give a crap to what anyone else thinks attitude, but for some reason some people can get to me. Flyboy escluded this really bothers me. I don't know why it would matter to me what some people think of me. I know I am doing right by me and my family (meaning my husband and girls), but still from some people I get this feeling like I am being judged or they dislike me and it really bothers me. Oh well. This feeling seems to come and go and with my brother in the middle of getting a divorse from my sister-in-law who I have known since I was 7! it is getting worse. I love my sister-in-law but since the marriage went down hill about 4 years ago she has been distancing herself from me and I let her. I am done at being the only one working at a relationship, I have become very distant from a few of my brothers who I was close to because they stopped calling me so I did too. Flyboy talks to his brothers at least once a week and I wish I talked to my siblings more often. Aside from my little sis that I talk to at least once a day I wouldn't know what is going on in my family it is not uncommon for me to not talk to my parents for months on end, but yet I talk to Flyboys dad about once a week. I hope my girls keep in touch with me and we can be close but I guess time will tell. I hate that I don't have a family and that they just kinda disowned me when I left MI, they did the same to my brother who lives in New Hampshire but he is happy to be disowned, I guess I am unsettled to how I feel about it. I will get over it I always do but until then I am going to wonder why do I let some people get to me?
