How can I stop someone from writing "The End"

I am completely at lost right now.

How do I comfort someone?

Everything seems so fine, we talked about all the random stuff we could think of. I've been waiting this moment to comeback here at my boarding house to check on my friend who's been struggling since online class started. She's struggling and I am trying my best to persuade here, to keep trying. Keep trying to live and face her problems head on.

Am I really trying my best?

I am not upset that it seems I don't know how to help her. It's not about me. I'm just lost of words and I can't think of actions that'll be effective for her to keep going on. She's having suicidal thoughts. A lot. I talked to her. Asked if she want to seek professional help. But I think it's not reaching her. I am not upset because I need to help her, but I just want to figure out and try harder. She mustered great courage to tell me how messed up she is, I want to treasure her trust and do something for her. Maybe this is why some people don't want telling someone their problems, because they don't want him/her to be dragged down along with their misery. However, there are people who are willing to be with all your miseries and pain. They just need a chance for them to help you.

I pray that my friend will be healed soon. She told me that it's fine when she's with someone. Because she get distracted from all those anxieties and prevents her attacks. She told me she's happy that I am with her compared to when she's alone, however I start to think I'll be away again after a month and she'll be alone again and I am not sure until when she can fight those thoughts. I want to stay here with her until she can get back on her own two feet. If my words won't heal her maybe my silence will. Sometimes people don't want to hear anything, just knowing someone is rooting for them despite all, I think it's a significant help as well.

I'm lost because I don't want to leave her alone here. I want to be with her till she can do it on her own, how've the problem is, if I stayed here for too long, I have to start preparing for my board exam considering that I am just self studying, I have to browse on books and stuffs- and she don't want to see anything related to our course. Yes, we're both Chem Eng Student but she have to retake some subjects so we're not classmates anymore since online class started. And our course is a major factor why she's feeling this way. She got frustrated and afraid when she see chem eng books, chem eng students, our blockmates, tshirts connected to our course, and even our lanyard or ID lace. If I stay here with her for too long what will I do? Should I give up my plan to take the boards so I will not cause her any frustrations? I am willing to do that, I just don't want her to know that I'll do that for her, because she'll feel really bad. If I will not review while I am here, what will I do? Part-time work maybe.

I don't know about everything but my priority is to help her.
