<human>: Can you provide a brief overview of the text?

So my friend was going through a tough time this year during high school. Around mid-terms she stopped coming to school. She missed most of her exams and I didn't see her until after Winter break (3 weeks in total). She didn't contact anyone and no one knew what was wrong during that time. I tried to contact her during this time. I ended up calling her mom and she told me that my friend was basically going through depression/mental breakdown. (Side note: The details were very vague but this is what I extracted from the whole thing.) Finally, she starts talking to me again, and we get together and talk things out over dinner. We got really personal about our family lives and I thought we really bonded over this. During this, she seems refreshed and ready to take on the world, like back to her old self. Fast forward 2 weeks, she starts acting strange again and ends up missing the rest of the school year. During her time being gone, I tried calling and texting to no avail, called her mom, talked a little, but ultimately never got to see her. I talked to her periodically over time. I found out she was in the hospital. I wanted to visit her there, but her mom was very vague about the whole situation again. When she got out, it was exam time for me so I feel like I slacked off in trying to see her... After school ends, she calls me, we talk, she sounds nervous, scared, and hopeful BUT we end up making plans and I tell her we'll confirm the day before our agreed date. I call her up the day before our date and no one answers the phone. Annnnnd now here I am. I don't know what to do.
<bot>: I feel like I haven't done enough to help my friend as she goes through a difficult time. Her mom is vague about her situation, and I know my friend wants to see me, but she's holding things back from me.
