That sense of abandonment will always be a part of you, it's not going to go away. but that's ok. let it be an indication of what you need in a relationship. And the right person will always do their best to give you what you need, not all the time, and not perfectly, but often and as much as they can.
You are kind, and sweet, and smart and beautiful. You light up any room you walk into, and you love with your whole damn heart. More than anything you deserve to be with someone who sees and appreciates all of who you are, and who wants to make you happy.
So breathe - you are ok, you are ok, you are ok. everything will be alright.
