Venting

I'am feeling a little frustrated. We have spent nearly the whole summer either helping or doing things with my husbands family. I would really like a break. Just a week would be nice. But they need help again this weekend.
When we went to the water park it was only supposed to be us as a family. But for some reason my husband invited his sister and then his brother came too. I was upset and a little hurt because my husband didn't even discuss inviting his sister with me. Is it to much to ask to do something as a family?
We don't do much with my family because everyone is so broken and living their own lives. We were never close growing up and it has just gotten worse. I will help when needed, but we mostly keep to ourselves. Less fighting and negativity that way. Bipolar runs strong in my family and without support and a great deal of self disipline, you can get yourself into a whole lot of trouble.
There alot of issues going on right now causing me alot of confusion. It is hard to focus for more than 10mins at a time. My husband has been dealing with alot of issues at work so I haven't been able to talk with him much. He works so hard, I really don't want to burden him with my problems.
I didn't mean for this journal to be sad, but I guess it is.  Oh well
