Lillamy and hopeful have good suggestions. I'd also check into "Meetups"--these are local groups who meet to do everything under the sun. You can google it and find out more. I've had some fun thru these groups doing hiking and other outdoor activities.
Volunteering might help you find people of like inclinations too--at an animal shelter, food pantry, public gardening group, Habitat for Humanity or any of the tons of other volunteer activities. Just googling "volunteer" got me a bunch of volunteer databases; adding your town or county gets more specific info.
If you try some of these things and don't find a friend, you'll at least feel like you had some fun and did something worthwhile, or at least that's been my experience in this area so far.
Congrats on realizing you need to get out and connect--I wish you all kinds of interesting adventures!
