So- I am an 18 year old guy with a loving family, a decent size amount of friends who are like my second family, and a girlfriend who I love. Despite all these things- I'm not happy. I often feel guilty because I recognize that I'm a very lucky person to have all this in my life but... I feel empty inside. It seems that I'm never satisfied with what I have. First I felt all alone and I wanted friends- so I went out and gain that over the years. Then I wanted a girlfriend and it was the main cause for my depression as I felt I would never find a girl of my dreams and as I was with friends- I met a girl who I fell in love with instantly and she is everything I could ever ask for in a girlfriend. Honestly, every day feels like a constant struggle as I keep fighting to become happy. That's all I want- is to be happy. I'm on anti-depressants but they don't seem to do anything. I keep pushing forward- telling myself tomorrow will be different but I'm starting to break down and give up as my grades are now all D's and F's. Please can someone give me some advice on the key to actually being happy or if I'm missing something because I'm trying so hard.
