Have you ever felt like saying forget it to everything? I am not talking about suicide, but just plain giving up. Pretty much just zombieing out and going through the motions?
I spent my life until I was 9 with a father in the Air Force, and after that I moved constantly, never really spent more than 4 years in the same place until highschool. I get to this point pretty easily, and I am very good at just dropping everything and moving.

I used to play Warhammer 40k and Fantasy, and I just got into it again because I feel like working on my Chapter Fluff.

Abandoning friends is easy, I get like that a lot and just drop people, I'm very lucky to have found a military brat as a friend, people on the outside don't get it and tend to hold grudges or not understand the urge to really just disappear, but one of my college friends is the same way because she spent her whole life in a military family, and we both get to the point where we disappear for a while, but we do come back and say sorry.

About 2 weeks ago I was trying to figure out how to kill myself effectively, all the ODing options turned out to require an amount of the drug that would make one ill before hitting, stupid LD50s. I finally figured on just chlorine gas in a closet, but I decided not to die recently and stopped self mutilating myself and got back on the whole life thing, but I found that I have issues now starting conversations with new people, which irks me since at the beginning of the semester I was known for my ability to talk to anyone.

The loss of desire is a temporary effect of depression. I spent 3 weeks not eating regularly and having a horridly irregular heartbeat, all from depression. It was hard to even go to school and my grades have been slipping. But it goes away, it's part of dealing with loss, and its really one of those grit your teeth and bear it things, which is horrid and is not what anyone wants to hear. You always look for a quick fix, and there really arent any.

You will find someone new, in time, but right now I'd suggest not trying to push out of your depression, but to push into it. Force yourself to think of things that hurt you emotionally, and keep at it, the more you think about it and face it the faster everything will pass by. And I dont mean fast as in 2 days, I mean weeks of agony, but over time it all will seem like its been handled, you've been through all of it, and you'll be able to stand back up and be fine.

I'm sorry you're feeling this way, and I wish I could help more, but really the only person who can help you is you, and it stinks even more that a characteristic of being depressed is a sense of powerlessness. I'm actually glad I learned all of this prior to my most recent state of depression, because had I not known as much as I do about neurochemistry then this could have gone on a lot longer and been a lot more damaging.

No matter how powerless you feel, you are the only one with power, dont grant that to anyone else, the only person with control over you is you.
