I’m so over it

I’m sick of being myself. I just hate everything about me. My boyfriend’s sister keeps saying how I’m too lazy and don’t do enough and need to man up. And it just makes me feel so horrible about myself. And my boyfriend doesn’t even defend me to her so it makes me feel he thinks the same. I hate being a horrible person but I can never change because I’m too lazy and selfish and unmotivated. I just want to sleep all day. I doubt anyone is gonna read this but I just wanted to talk about it I guess.
