Selfess v Pushover

     When does "too much" start becoming "too much"?  You're supposed to help people whenever possible, right? Right? I'm starting to think that that might not be the case.  In high school I have always been one of the main go-to girls whenever someone had a question or needed help with something, and I've never been one to complain about it.  I think it's great that so many people trust me enough to allow me to help them, but lately I've started to think that I'm spreading myself too thin.  Whenever somebody asks me for help I immediately put their needs as first priority; anything to make their lives easier, but what happens when their needs start getting in the way of any of the little "me" time that I have left?  Is it okay to be selfish and deny them assistance sometimes? Is that even considered being selfish?  All I know is that inside me there is a roaring debate on what I should do.  On one hand, I really do love helping people and if I start denying them help they might never come to me again.  On the other hand, I think I might go insane if this keeps up the way it is.  Sanity over high school sainthood, or high school sainthood over sanity?  I definitely don't want to become somebody that people hate; I've worked hard to make sure it's the opposite, which I guess is why there isn't an easy answer for me.  Regardless of how deprived of thinking time I am nowadays, my sense of logic is still intact, and I know what I have to do: I have to be "selfish" instead of bottling up everything and eventually exploding (trust me, that will be much worse).  I guess it's not about caring for yourself more than others, it's about caring for others so much that you wanna be the best you can be...even if that means taking a break every once in awhile.
