Crushing hard

Alright ladies.

I'm crushing hard on this boy. He's super amazing and fun. He's exactly what I'm looking for in a significant other and I just want to be with him and learn and grow with him as a human being.

He knows I exist, his last girlfriend was pretty skinny and I am not to say the least. I recently lost 50 pounds and have plateaued but seeing him tonight makes me want to continue losing weight.

I know that losing the weight won't give me all the confidence I need to date, but i believe it's a start. I want to date (him especially) so bad, but there's something wrong with my head that convinces me that I am unworthy or undesirable or that I can only just be a friend with anyone that I meet.

Has anyone else experienced this? What can I do to get over it?
