“You have a terrible temper”

Apparently, I used to be the closest thing to a perfect child who never got mad or was never even the slightest bit disagreeable. Now, my parents keep telling me how much I can’t handle rejection, how terrible my temper is, how I’m so much more emotional and I don’t need to be, etc. I don’t get it??

Like I’ll experience something like getting rejected from a college I liked and be upset about it and they’ll laugh and then tell me how bad I am with my emotions,

Or I’ll reasonably be angry at the dog (who isn’t trained) when she claws/hurts me because she doesn’t listen to me when I tell her “no” and “get down, stop scratching me” and they’ll say I have a terrible temper.

Another thing, I get upset (not terribly, just a reasonable amount) when people belittle me. My parents always tell me that it’s not something to be upset about and occasionally blame me. I just don’t like being belittled/disrespected for no reason. I don’t think it’s hard to be decent to another person.

I know it’s unreasonable to be emotional sometimes, sometimes I’m irrational and it is my fault. But, I can’t help but feel like my emotions are being invalidated, and I feel so much pressure to find a way to just not feel them so that I can conform to whatever my parents want me to be. I don’t know if I explained this well or if I’m just making something out of nothing. I just think my parents want me to be something that I’m

Really not anymore, but I don’t know how to tell them that without making them mad at me.

Side notes: I don’t hurt the dog in any way, I may yell to try and get her to stop tho. Also, when I say upset I don’t mean crying, I just mean unhappy/disappointed.
