Yes, you do have to fix yourself before you can create stable interpersonal relationships, because what happens is that you can end up bringing some of that negative energy into whatever relationship you find yourself in, creating a burden for those around you.
This could then lead to a negative feedback loop where you lose your friends/partner, and end up hating yourself more.
If no one’s going to love you, you might as well love yourself.
