<human>: Hi all, I'm (male) a lurker around here .

My sister died several months ago. We had a very close relationship and were also very close in age (I'm 24 and she was 22). Recently I've been becoming more sad and depressed because of it, where work is very difficult to get through and my motivation and willpower is weak.

I'm particularly concerned about my relationship with my girlfriend (we've been dating for about 2.5 years and we're the same age). We are very close and have gone through a lot together, but I find myself becoming withdrawn from her. This is along with the fact that I actually don't get to see her very often because I'm so busy with work. I love her dearly, but I get the feeling that I need some space since my world has been turned upside down. But I also don't want to ruin what we have, which is a loving and understanding relationship.

Any thoughts or shared experiences?

Can you provide a brief overview of the text?
