Almost bumped into each other again

Lately, my daughter's been going out all the time and doing whatever she wants. My blood pressure is in the 80s, and I feel dizzy just moving around. When she comes home, she complains, 'I'm hungry' or 'My head hurts' about dinner. I do make it for her, but when I ask her to heat it up, she says she's tired and asks if I can do it. If I manage to get it done, she spills soup on the floor and gets yelled at. That's my daughter for you, only thinking one way. She has ADHD... Isn't she too old for this? Because we're parent and child, emotions get involved, and I get angry regardless of her condition. I wouldn't feel this way if she were a stranger. I could go on, but it'll be over soon anyway. We're both at fault. I know that, but still.
