Self Love and Trust

How are we supposed to love others, if we can’t even love ourselves? I heard something along those lines in church and felt personally criticised. Of course I can love others, I love them so incredibly much, but myself? no that seems to be something I’ve never truly been able to do. I’ve been content with who I was, what I looked like, but loving myself had never been part of that. It seemed so easy to love others, I could give away every ounce of me loving others and I would do it in a heartbeat, but taking just a part of that for myself just didn’t quite seem plausible.
