Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.

Go knock on the door. If she answers, start with "I didn't even get your name today."
If someone else answers, say "the girl who lives here was kind to me today, and I didn't even get her name. If she's home, can I speak with her a minute, please?"
or whatever version of that that works for you~
You are here saying you said all that stuff and your so called friend ignored it.
Maybe this kind girl is sitting there wondering if you are okay, and feeling concern for you but can't come knock on your door to find out because she offered you the branch of friendship and now she has to not be intrusive and wait for you to offer one back.
If it were me, nothing could keep me from knocking on that door~
good luck hugs
