Is it normal that i become enraged when people waste my time and energy?

I become so angry when my husband, family, or friends waste my time and energy.
EX:
- When they ask a question, I start explaining, and half way through my sentence they cut me off and forget I was even talking. This can be an exhausting waste of energy for me... especially if I have to start the explanation over several times.
- When they ask me to do something with or for them and then make me wait before we can get on with it (Sometimes 10 mins, sometimes all afternoon...).
- Sometimes they make me wait for them and then decide they don't want to do the thing after all.
- When they say they want my help, but won't tell me what they want. I exhaust myself trying to offer different options that they use passive aggression to deflect. They do not tell me why, or what I can actually do to help; however, they do continue complaining. I find out later that I was completely off base and trying to solve the wrong problem. Maddening.

There are many more and varied examples, but this should give you some idea without taking up too much of your time ;)
