If you have to love yourself before you can love someone else and nobody will love you if you don’t love yourself doesn’t that mean you’re unloveable?

No. Loving yourself is embracing the authentic you. It’s knowing your worth. You can love on your terms instead of changing yourself for others. No one is unloveable and you can love abundantly without loving yourself; however, loving without loving yourself is cheating you out of how precious and valuable you are.
