Also, lastly I've told you I've been through hell in my life because I have. More hell than anyone should have to go through but during my teenage years as I said I was secluded out of depression.You can't compare your situation to that when you didn't go through anything like that...I have. I am not as lucky as some of you are.

If you're blaming this "depression" on some acne than that's an extremely silly excuse. 

That's pathetic. I highly doubt you could go what I went through. In fact, knowing what I went through I'm positive you probably couldn't go through it. I won't say you can't because you have never been in that position but coming from someone who dealt with it and constant suicidal thoughts, I know how bad it was. Notice I specifically said horrible acne. Cystic acne to be more precise. It wasnt a few pimples. It was bad enough to destroy my self esteem and make me completely secluded from nearly everyone. 

I would like to add just two more things. One, I never expected him to hand over the car for nothing nor asked him to. He approached me once about buying from him which I said I'm not sure because I didn't have the money then and i didnt know they wanted to sell it so quickly. He never even gave me a heads up when it was sold, I found out when I heard some guy coming over to pick the car up and that was it.

He didn't say a word till me until much later on when both he and my mother knew I was upset about it. If I had to I would have at least give them something but it's bullshit anyways when they say they need the money only to spend more of it on another car. Secondly, some of you seem to think I have it out for him. I won't deny I don't like him but at the same time we were close and it's a love/hate relationship. I had reasons for my treatment towards him for how he treated me at times.

My sister mentioned to me earlier that my mother and him could break up over this. My mother can do as she wants and I will tell her that the next time we talk but I will also tell her I DON'T want them breaking up over me. If it's been brewing (they have had fights but I cant speak for their relationship) and it's what she wants fine but I won't cause a rift between my sisters, my nephew and even our pets as my mother and him him take care of them for the most part.

Occasionly I feed my dog, cat or turtle if need be. This it out of routine because my mother feeds my cat in the morning as she wakes up when she works, he feeds the dog during the afternoon and he feeds our turtle. I used to feed him but Eric told me he will take care of it and I left at that. 

Especially because I know he greatly cares for her and I won't have it end just because of me.
