Im not sure what to say to my best friend

I've known my best friend since 4th grade and we're going into our sophomore year together. Our freshman year was pretty bad in all the ways and we've both changed a lot. Ever since October/November I've been struggling with depression and anxiety and I've recently opened up about it to her only a little bit before her step brother was lost to suicide. Ever since then we've both really been struggling and we got to a pretty good state for awhile where it seemed like we where back in the 4th grade. Recently she was put on meds and then went off them and she got really bad so she's back on them now. But recently she had something happen to her and I have no idea what or how bad it is because we're barely talking. I don't want to see like I'm forcing her to tell me what's going on I just miss her and I want to talk to her cause I'm not doing great either rn. So if anyone could give me advice on if I should just keep giving her space or try to talk to her/what to say to her you would be my hero !
