Who cares?!?!???

Why do I care so much about what other people think?
I can say I don't care what people think but reality is a small part of me does... I can't control it and I can't explain it.

For example: Saturday I went with the family to a little carnival down town and the baby diva is teething on top of having a small cold with that combination she was just not wanting any part of the fun. She literally freaked out and threw herself on the ground several times kicking and screaming. Although I handled it the best ways I could I was extremely embarrassed. I try my best to be a great mom and I want that to be known so when she freaks out like a normal kid I can't help but wonder what other people think and I get upset and think about ways that I could've handled it differently.

Another example: Last night I went and worked out. Even though I was running on a few hours of sleep and thought of about 100 different reasons as to why I should stay home and relax I went anyways. When I got there I noticed that there was a girl there that I used to be friends with. I ended our friendship for a few reasons. One of which was her husband disrespected me several times in one day and she actually witnessed them and did nothing. And another reason was she was only nice to me to get me to sell Herbalife products for her. Although I liked a couple of the products I no longer use those products and to be honest I only used them for a couple months. I also used to workout with her at a local boot camp that she hosted. I did enjoy those workouts but  I don't like fake people and I don't like women who let their men be dicks to other people. PERIOD. I have no respect for her.

Even though I got a great 45minute workout (normally I never go for less than an hour) in and should be focusing more on my accomplishments of making it to the gym after a long night before and day all I could do was look in the mirror and wonder if she thought I had gained weight since I last saw her which was about 6+months ago. If she thought I looked great even though I wasn't going to her boot camp workouts.

Now that I'm sitting here thinking about it I can't help but wonder why?
Why do/did I care what other people think? I should only care about what my husband and I think. And not to sound rude but the only opinion that really should matter is my own. This is my body. My temple. My journey.So why do/did I let that bother me on two different occasions?? And those aren't the only two that have ever happened those are just the two most recent.
