am I wrong for this?

I was with my friend who is a little older than me and she was giving me advice about things like being nice and positive. Ik usually depressed and don't like to go anywhere because I do not have the motivation. After our chat I became really optimistic and had a very positive outlook on life. I went to text some of my friends in our group chat, and a girl who I am really good friends with tells me to go for it and to start being more positive. She's kind of like me except she thinks her life is way harder than mine. I decided to text her and ask her if she wants to join me in my "quest for happiness". She said she couldn't,  that she was too depressed. I asked her to stop sending me depressing quotes and music. She said "sorry" then ignored me ever since. Did I do something wrong? Was I too harsh? Should I keep her out of my life or try to help her with her "depression"?
