need some advice - i think

[Moonbeam]

its been quite a while since I was last here.

I am just at such  a loss right now. I have a friend with depression and on meds for it. I read how people turn their backs on friends with depression, but i am the opposite - i want to be there for them, i want to help and i would like it if they did talk to me, instead they go quiet and i don't hear from them for weeks at a time. This in turn is making me feel miserable. Its not as if my friend is local, we do rely on a social media site to keep in touch, but i struggle with the silence. I genuinely miss talking to them. 
Any advice please?

This isn't going to be the advice you want but all you can do is keep carrying on the way you have been with your friend.  I have had the same issues with a couple of friends but I just keep sending messages so that they know I am thinking off them and be patient.  On the other side of the coin when I am very depressed I tend to go very quiet.  Friends have learned to be patient with me as well.

Completely agree with what Pip said. When I'm at my worst I can go for weeks without talking to friends, but I know which friends understand and know that I'm not deliberately trying to push them away. All I can say is you have to be patient, just make sure that they know you are there for them, without making them feel pressured into explaining their feelings to you. It may take a while, but once they know that you aren't going to abandon them, they will feel much more comfortable opening up to you. Like Pip said, if you don't hear from them for a while, just drop them the occasional message to say that you're there if they need to talk, or that you'd like to hang out when they're feeling better.
