Hello everyone, I am 18 and recently started university. I have a girlfriend and a very active social life, yet I feel depressed and empty quite often. This feeling isn`t new, I`ve had a similar on and off feeling of emptiness for around 5 years. The thing I don`t understand is that when I`m with people I`m the loudest most outgoing person there, people think i`m funny, social interactions seem to distract me from any sad thoughts. My concern is that recently I`ve been sad more often than not, and have been feeling numb most of the time, even during social interactions or time with my girlfriend. Though I have no specific plan, and have no real intention I don`t think of killing myself... the thoughts come up quite frequently, often multiple a day. What should I do?
