If you really want to write, you enjoy it, and you persist at it, your work will eventually improve to the point where you'll start to get published and noticed. None of us can know how talented we are. It doesn't matter. You can learn the craft and become very good at it. And you can enjoy it a lot.
Rejection is an inevitable part of writing for publication.
You can't learn if you don't fail. I had a zillion rejections, but that's what showed me what worked in the marketplace. It's much easier to tell someone who is sensitive to rejection NOT to feel that way, but the more you know about the process of publication, the better. It's really not YOU that's being rejected. I did that a lot.
