I've been down this road all too often when I was young, but feeling is a part of nature. We can't hide from it, the more we run, the more exhausted we become. I feel like it comes from not feeling connected with another being, not being able to truly communicate to those closest to you. It's not about the quantity of friendships, but the quality of them. Keep looking for good friends to stay in touch with. True friends will always help when times are tough.
