Feeling shitty

My life sucks. I hate my life an my family. I'm 195 lbs and I'm only 15 I'm tall 5'9" so I use it as an excuse but I'm fat. Nobody wants to date me. I like this guy named Isaac and we're friends but he's always talking to me about other girls he finds attractive. Not once ever has any male ever told me they love me. Not a dad, mot a brother, not a boyfriend. Only my mom and my 1 friend. Everyone else in the work hates me. I'm huge and ugly and fat and I just need to die. I hate my life but I don't want my mom to be hurt to I'll wait until she dies. The day she dies.... I'm out.
