There is a saying that says: “No one will love you until you start loving yourself” like it’s supposed to be motivational bullcrap. I sincerely detest the saying, because it basically says that you’re not worth loving until you love yourself. It’s such bullshit I don’t even know what to say.
I had trouble to love myself in the past, I think it’s something most people go through at least once. But it does not, under any circumstances mean that you aren’t lovable. Everyone is lovable, no exceptions. There are going to be things that people love about you that you don’t and vice versa.
