My boyfriend/best friend bores me?

I've been seeing my boyfriend for about a year now. The problem is he bores me. He's sweet and kind, but not very outgoing or funny. He's also currently my best friend. I'd dump him if I wasn't so emotionally attached or afraid of hurting him. After an incident with losing my best friend (and consequently all of my other friends), he's been the only person I can trust or really talk to for the past year. Our group of friends has also started to bore me. I feel stuck and I feel too negative and uninteresting to try and reclaim my old friends somehow and there really isn't anyone new out there that fits my interests to (attempt) to befriend. There's also no contenders to fill a boyfriend slot either, I've ALWAYS been too picky and me starting to date him was more of a happy coincidence. He was never really my type. What should I do? I'm tired of feeling depressed and lonely, but scared of being more alone without him.
