Welcome to Psych central ((((Samuel)))) yes, you have described depression quite well. It's a nasty beast, I know. IMO, you have already confined/committed yourself... to your dad's basement? No, many ppl do not and never will understand mental unwellness... I'm sorry you had to realize that fact.
What you DO need is someone to talk with! There are many members here who will do that in chat with you, and here in forums, but mainly you need someone IRL (in real life).. who KNOWS depression and can help you counteract it's lies that it tells. CBT is a great counter for depression, as are some of the newest meds. You DO need outside help; depression does not get better on it's own. There are members here who can list the resources you MUST check with for assistance... if you have sent this to so many outlets, you can do this IRL and find a clinic or something that will help you begin to heal.
I'm sorry you had to find us, and need PC, but glad you did... come back and post often!
(Welcome zuzu, didn't see you sneak into PC hehehe I've been busy battling a hurricane here in South Florida!) tc
