I like to feel needed

As my sisters all know, I am having a hard time with them all living in Edmonton. I will be honest, I just don't like it. I miss them like crazy! I miss seeing them when I randomly pop over to my parent's house. I miss talking to them all the time about their lives. I just miss them. I think that I miss them so much because I am their oldest sister and I have always felt responsible for them.
When we were young and my parents would have us clean up a room, I would divide the room and let them pick which side they wanted to clean. (They always chose the easier side of course) and I would clean the other side. Well, my side would get cleaner faster and so then they would decide to switch sides and I would do it. They thought that they were so sneaky, but I realized that I just wanted it to get done and a little help was better than no help at all.
And then there was my candy jar. I have never been a huge fan of candy. I just don't really like it (good quality chocolate doesn't count as candy, it's a dessert!). And so at Easter time and Halloween and Christmas, whenever I would get candy I would put it into this little rubbermaid container and I called it my candy jar. Then (being the oldest, and slightly lazy) when I would want my sisters and brother to do something for me that they didn't want to do I would bribe them with candy. It pretty much always worked and I usually got whatever I wanted.
And now they are in Edmonton. I have felt really lost actually. It used to be nice to have my brother around because we would hang out quite a bit, but now he has gotten a whole bunch of friends to go and live in his apartment complex and he is having a blast over there.
When I moved houses, I wanted to make sure that I moved closer to my grandparents. I wanted to be able to help them out and, let me be honest here, my Grandma is pretty much my best friend. So I moved to be close to them. . . and they bought a second "Playhouse" in St. George. So, they are pretty much gone for more than half of the year.
And then there are my parents. They are now empty nesters and very busy. They constantly have things going on and I think that they are really enjoying not having to worry about anyone at home. It seems that they are always going places and it is fun to hear about their travels.
So, that just leaves me. I don't know if its because I am the oldest, or if its just my personality, but I need to feel needed. I love to do little things for other people, especially my family, and with everyone being gone I just am not needed. I feel weird. I don't really know what to do. This has actually really started to affect me and I think that I need to make some changes in my life. My babies are getting older and so they don't need me as much. I think that is part of the reason that I got this puppy for Otto. Now I have someone who needs me again.
However, I can't go on buying puppies because we have just run out of room. So, I need to change something, or do something that will shake things up enough that I won't need to feel needed.
I guess I just need to think about it for awhile.
