I can relate to this. It's a lot like what I've been feeling the whole year. I don't have money, but anything they need, guess who they call? I joke of being costumer service or technocal support, because they call me even when they just need to put their cellphones on vibration.

And yep, I can't say no. I don't know why, but as much as I need to tell them to go and do things themselves, as much as I would like to tell them that I am not their servant, I end up doing all kinds of things. What I've learned to do is as simple as don't pick up the phone, don't answer their texts, don't read their emails or private messages. If I can't say no, then they won't find me to ask for anything.

I think sometimes they need to do things by themselves. It's not just that I am fed up, but also that, for example, my uncle needs his daughters to take care of him, not just me! My cousins also need to look for his father if they don't want regrets later. I need to stop buying my single aunt so much because she is spending all her money on someone who is just using her. Sometimes we need to teach them to be responsible and we can only do so by not helping them everytime. So, if I know I won't be able to refuse to do what they aske me to, then I just disappear.

Good luck!!!
