Feeling Bad

Some of you may know that it takes a lot for me to get mad. MOST of the time I just brush things off and try to not let things bug me. I joke that I live in this perfect little bubble, and I don't like people who try to ruin it. I like to have a positive outlook on life.
Any way I haven't been feeling good for a while, and all the kids have been sick for 2 weeks. I have just not been in a good mood.
Last night I had just had it with my family. I am tired of being the mature one. When I do something I own it, I don't pass it off onto someone else.
Some things have been going on in my family and I am tired of being the one that hears about how so and so did this and so and so did that. It amazes me to see how selfish people are. And how it is always everyone elses fault.
It is frustrating to me that sometimes I am the only one who can see the whole picture.
I know that it isn't easy living with family, but when you are living in someones home you should respect their wishes no matter what they might be. You should keep your rooms nice and clean, and help out when asked.
It is like I said on the phone to my dad, my grandma is my best friend, I would do anything for her. It kills me to see her hurt in any way. She isn't going to be around that much longer(3-10years), so lets make it enjoyable for her while we can.
Can't we all just get along?
