Everyone leaves

People used to care and ask me if I’m ok a thousand times a day. People used to care and ask what’s wrong when I was shaking my legs. People used to care and comfort me when I was staring into the distance. People used to be worried about me when I was laying in bed all night drowning in my music. But now no one does. All of my friends replaced me, My parents just keep saying that I’m lazy & everyone else just doesn’t care. People always told me to talk about my feelings because they “care”. But as soon as I started talking about it they just thought that I’m annoying or dramatic. I just don’t know what to do anymore. If I give up I’m “selfish”. But I just can’t keep living like this. When I’m at school I’m always alone. When I’m home I just lay in bed all day because my mental health won’t give me motivation to do something. I just need help.
