I've started telling some family and friends about my plans to RE this year...Now, I know I won't be bored...but I wonder about the lonely part, since my friends will still be working...How do other people deal with negativity, and not let it get to them?
I think you'll find so many like-minded people once you start looking around. In fact, Mrs. & Mr. Frugal Woods (and their Frugal Hound) will be your neighbor in two short years - you can start there! See

Of course, it's hard to not be understood/supported by family/friends (I know, my parents grew up in upstate NY and went counter culture - not an easy path back then. Much easier now - there's more company for you out there.) I think your plan of action needs to include building a supportive frugal/FIRE community. I'm not saying to cut your family/friends out - just give yourself some support to follow the path you've chosen.
