I called my trainer to ask what time I'm supposed to be there tomorrow because I forgot if it was at 7 or 8. Well she just started yelling and pretty much told me she doesn't have the time to check and if i can't remember things myself I shouldn't waste her time. She's one of those people I get overly attached to and when she says something nice i feel like she's the best person in the world and when she does something I don't like I switch to hating her. Because of this I have no idea if i have a right to be upset or if I'm overreacting. I really want to cry and never see her again right now. But i also know that she's pretty busy so I  can kinda understand her. 
If I'm overreacting then what was I supposed to do? Not call and show up at the wrong time?  Cancel it? Just not go? 
Also I don't think she's ever been on time and I'm usually there waiting for like 20 minutes. 
This is the kind of thing that a normal person would just  forget about in 5 minutes but here I am hours later wanting to die because I feel like I'm worthless and just wasting everyone's time.
