<human>: She's not my aunt exactly, more like a very close family friend. She was my mom's best friend in college. 

When I was 11, I stayed the summer with her and her family. It was honestly a pretty shitty experience. I was homesick and didn't really like her children or husband that much and felt like an outsider most of the time. Anyway, she saw me cutting the legs off a spider with scissors and cutting the wings off a moth. She also probably found out that I poisoned her neighbor's dog. I honestly don't know why I did all that. I can't really explain. 

She also knew I was lying about some minor furniture damage, but I didn't tell the truth because I was afraid of what she would think of me because my mother had been and is emotionally abusive. I remember that I wanted to tell her that it was me but couldn't. I also lied about being on my period because at the time, I was ashamed of it. 
   
Her daughter didn't like me, and her son was little but said I was ugly. And that sort of impacted me I think because I felt unworthy, so I guess that made me want to hurt weaker animals and myself.

Also related is that my mom tells her everything, so she knows two instances that make me look even more sociopathic. Specifically, that I brought a weapon to school and that I made threats online that lead to a police investigation. She may or may not know of my self harm. 

Right now, to everyone, it looks like that I cleaned up. I go to an Ivy and I have an internship with a tech firm in her area. My mom wants me to stay with her over the summer, but obviously, I'm not really down for it, and I highly doubt she is either. My mom hasn't asked, but I don't know what to tell her to convince her that this is a bad idea.  And I also don't think it will be possible to clear up this misunderstanding with my aunt.

Can you condense the text into three sentences or less?
<bot>: Aunt caught me abusing animals and lying and thinks that I'm probably a sociopath. Mother wants me to stay with her over the summer. This is a bad idea.
