Tired of carrying everyone on my back

I have to take responsibility for a lot of stuff I don't even need to but I do because nobody else is stepping up to do them. I'm tired and close to just saying "fuck it do it yourself". I don't say much, I'm more of an observer. I've seen some pretty bad choice coming from some of the people around me and I want to say something but at the same time I don't feel like I have the right to say something. The way I see it is that of you don't care enough to help yourself I shouldn't go out of my way to help you out, if I see that you want change I don't mind helping out. I have major bills that I need to pay and so I work hard and make the money and save, others have even greater responsibility on their hands and don't save or plan anything. I have a lot of love in my heart but little compassion for those who expect others to pick up their slack.
