VBC, I felt that way for many years. At times, my loneliness felt like a black whole that was going to swallow me whole. It wasn't just that I was single; my family, and my parents in general, doesn't really live me in any sustaining way. The pain that caused was never-ending. I spent many years and many hours of therapy to get to a better place. CBT helped tremendously in recalibrating my internal dialogue. Yoga helped me find some calm in my mind, along with some joy. Together, they helped me detach enough from some very pervasive and powerful thoughts and feelings, for some new thoughts and feelings to take root. I'm not going to lie; that didn't happen overnight. So, the best I can suggest is to stick with therapy for as long and frequently as you can. Build in some form of meditation, mindfulness training or yoga if you're so inclined. The article Oak posted is excellent, too.
