That's all she wrote. (Literally)?

Been with my girl for 6 weeks, (not much, I know).

In the beginning she was replying at a fine pace, then I stupidly told her that I didn't want to talk via phone that often (my mistake, I now know).

Somewhere around week 3 she stopped replying so quickly and often (basically 10 messages a day or so), so I talked to her about it. She mentioned that I told her not to reply that quick, so I told her that I was wavering in my attraction toward her during, and that I now want her to message me all the time, for I am fully dedicated to her now.

Nowadays she messages me very rarely, and yesterday I talked to her about, she said she's very depressed and was for the past 2 days.

I know what she's going through because I feel depressed often also, and it sucks, but when I'm feeling like that I prefer company, she said she just wants to be alone, so I gave her space.

She didn't message me all day yesterday, and today it's almost 5 and not one message... I'm worried and I want her to talk.

Also, we haven't gone on a date for roughly a month, I've been trying to hang out with her any chance I get, I tell her I can do it before work. I tell her I can come after work (I end at 1am) and one time I did, but she didnt pick up.

I wanna be involved in her life, I want to hold her again and I want to help her through this, but I... I can't?

Please, give me advice.

Background info: She's 18, I'm 20. She used to be suicidial, but I helped her through that. She's a cancer, I'm a leo (if that helps)
