<human>: Can you provide a brief rundown of the text in within 3 sentences?

A little background: I suffer from low self esteem issues and anxiety from years of verbal abuse that came from my parents. I also have hypothyroidism that fluctuates my weight a lot, and I've recently gained back about 20 pounds it took me 2 months to lose. 

Lately, I've felt extremely down on myself, everytime I look in the mirror I hate what I see and I feel like I'm the ugliest person in this world. I've felt really disgusting since I gained back weight I struggled to lose due to my thyroid condition not being maintained, and stress about my new job and finishing school. I've told my boyfriend this, and he always tells me how much he loves me and how beautiful he thinks I am despise what I think.

But yesterday we were watching a show that featured a lot of "fake" porn stars, and I cracked a joke about how one of them looked ugly because her hair looked like a 5 year old did it.
He turned to me and said "Sure, if that's what you think." I asked what he thought of her and his response was 
"I mean look at her. She's smoking hot, look at that body."
I looked at the tv and down at myself and this wave of sadness hit me and I felt like bawling because the girl on tv had to be at least 75 pounds skinnier than I am. My boyfriend has never even said that about me in the last two years we've been dating.
When I turned away upset, he said he didn't mean for it to hurt me even though he knows the issues I've been going through, but I asked for his opinion so he didn't really want to apologize.
 Am I being too much of a crybaby?! I mean i just want honest opinions, am I overreacting?!
<bot>: been upset with myself since I gained weight back. BF made a comment about how he thought this skinny woman was smoking hot, but has never said that to me. Am I overreacting by being upset???
