I have some friends but am trying to learn to be a better friend to each of them, I've always struggled with not falling out of life. We live a weirdly social life in this house, but I get very anxious before almost every event. We're also in the SCA (Society for Creative Anachronism) and a few times a year dress up in early Renaissance garb, camp, and socialize with others that way. If meeting people is the issue think about your hobbies and go to the places where others with similar interests hang out. The suggestions above for classes, events, and activities are terrific! The amount of time is finite and you can hang out on the edges until you feel comfy. :)
