>I felt scared of over-exposing my own eagerness. Of making myself too available, I guess?

I'm not sure what you mean by this. I think you may just be overthinking things. He's already seen you many times, so I don't think it's going to bother him if you're not looking your best. How is being available being too eager? And how would he know if you made yourself available or not? I think you should plan a makeup for this as soon as you can. Good luck!
