I'm going to stop doing tech support for my friends and family who are all self proclaimed tech illiterate.
Do you think ending this is going to be something that helps you or hurts you?
I really do not know. I just think that they are taking advantage of me.
Your friends and family need your support in tech matters and avoiding that because you don't like them being helpless is not correct. Help them to learn about tech instead of punishing them.
I'll think about what you said, I've been feeling empty lately.
While you may feel a little used provided all of this tech support, just understand that you are truly doing something nice. While your family may take you for granted every now and then, you are ultimately doing the right thing. Do not be afraid to let your family know how you feel though!
