Do you push him away when you need him because you think you'll annoy him?
I feel like I'm an annoying person, and I hate myself for being the way I am. When I left my old friend group I didn't want to join anything new because I guess I just assume everyone hates me as much as I do, and just don't show it. I knew that I had to get out there and meet people though, so I joined the anime club (they can't kick me out of a school organization), and I was like "I'll be evil and annoy them on purpose by being there and attending the meetings." Now I'm great friends with them! I just had to trick myself into being the bad guy thinking I'd annoy them by being there, and they didn't end up being annoyed.
So, even if you think it'll annoy your boyfriend in the short term, he might appreciate you being open and honest with him. He probably wants to support you.
Either way, I've never had a girlfriend or anything, and school clubs is pretty different than seeking help. I'm not sure if my advice applies at all, but I hope it helps!
