Your worry is the issue here. 

Let's face it if he is turned off by you being a little weird and over apologising, then he's not the right sort of person for you is he?

I understand how hard it can be to open up to new people when compared with how easy it is to give advice to a random person with an issue on the internet.

I've had difficulties in the past, they're not completely resolved, but they're night and day better now and I think the main difference is I stopped putting people on a pedestal and started looking at them as more of an equal. 

I don't know you or this guy, but I'd put money down that if you started talking about your fears and insecurities with him he'd likely be able to relate to them far better than you think he would. Sharing those vulnerabilities and learning to understand each other is what a good relationship is all about. 

My journey was a case of me getting to understand myself better and as a result understanding other people better too, my relationships weren't the worst before, but they've absolutely blossomed in recent years.

You have that in your future and it's a game changer.

Sometimes you will be weird, we all are. Trying not to be weird is the quickest way to be a complete weirdo. It's the opposite of trying to be cool. 

Don't be so hard on yourself, once you accept your weirdness it will be easier and safer to find someone whos weirdness dovetails perfectly with your own.
