Sad And Sick Of This

First off, my boyfriend and I have been together for almost 2 years now. He lives in Canada and I live in the states, so yes, we have a long distance relationship and up until now, it has been no problem for us. We don't get to see each other often but we usually skype every night for at least a few hours.

At the end of June, my boyfriend's uncle passed away in a totally unexpected car accident. Only a week later, his younger sister came to visit him and he had to put a smile on and just pretend everything was okay so he never really got a chance to properly grieve. About 2 weeks later, he found out that his friend from home had committed suicide. He has been seeing a therapist now for about 2 or 3 months and he and I have not skyped in 3 months. I get a text every once in a while. I am trying hard to just be patient but it is difficult when I literally cannot do anything to help. And I understand that it's not my battle to fight-it's his.

He is usually a happy, very outgoing person and now he's totally different. I am just trying to ride things out as I know that's all I can do right now but I am so afraid that our relationship is going to end because of all of this. I know, I probably sound selfish and I should be focusing on him but it's impossible when he doesn't respond to my messages or doesn't want to talk to me. I'm trying not to take things personally because I know the way he's acting are just symptoms of depression. Does anyone have any advice? I just need to know that I'm not the only one going through this.

Thank you all.
