I agree with what others have posted. Some of the things you said sound exactly like what my son (18 y.o.) said about himself last fall. Everything seemed boring, he had no idea what he wanted to do with his future, life felt like it had no meaning. He also plays lots of video games, as a way to relieve stress.

Somehow he was able to tell his father and me what he was going through. At that point he was near rock bottom because he had been feeling hopeless for quite some time. Anyway he is now in therapy and taking a low dose antidepressant and his outlook has really improved. He still has a ways to go, and he decided to take some time off before going to college, but now he has hopes for his future.

So I strongly recommend talking to a doctor and getting yourself some help. You are worth it!
