Why am I always the one doing all these??

Why why why??? Why am I always the one? Why am I always the one who feels the need to be responsible for all these little things? Why is it me & no one else? Why do I need to take care of this and that, do this and that, check this and that, buy this and that? Why can't that someone who should take charge take care of all these things or at least share the workload with me? I wish to be taken care of as well, but why are things happening in the other way round? I hate it! Why are things like that? It's just not fair!!!
