I just want to start out with the fact that I do not suffer with depression myself, but I recently became friends with someone that does. I didn't know that she was suffering when I first became friends with her, but after talking with her every day she has shared a lot of her struggle with me. I have tried to be very supportive by letting her know that I'm here to listen and we have had many open conversations where she has expressed her thankfulness for finally having someone that she can turn to. However, she does experience really difficult stretches where she shuts everyone out and does not respond to any communications (phone and texting has been the extent of our friendship). I really want to help her through the tougher days but can't get her to reply to anything lately, every couple of days I send her a text just letting her know that I'm here when she needs someone to talk to. Any advice on anything that I can do to help her would be greatly appreciated. Thank you.
