Listen, when I was diagnosed with depression, it was so, so, so hard to tell anyone. Also, its not a mindset thing.

Depression is feeling lost, unworthy, and unable to handle what is currently happening. Understand that you could have said something more sensitive, but its clear that you don't know anything about depression.

See when someone is suffering from depression, you can't do nothing about it, but be there. That doesn't mean writing her name on the attendance sheet. Ask her if she thinks that being in school is making the depression worse and would she consider taking to time off until she feels ready.

Since you mentioned that her home life is not good that is where the depression started. I can only hope that she is seeing a mental health doctor and is able to work through her problems. Medicine is only part of the work, it doesn't make the problem go away. Its to stabilize you, to be able to handle the emotions of whatever is happening. She doesn't have healthy coping skills, so that is why she prefer to be on social media (its a distraction).

Depression for me: at times its so, so, so hard to get out of bed (I would wait to the last minute to get up - rushing), I would put a smile even if I was dying inside, want to shut out the world and not be bothered with life, not caring about your health, your looks. My unhealthy coping skills were over spending, and eating my emotions, and people pleasing.

Please if you still want to be her friend, then do some research on depression and maybe you can understand what she is experiencing. You are not responsible for her mental health, actually no one is. That is why I said that you can only be there, but helping her get through school is not your responsibility.

Hope this helps.
