<human>: Can you succinctly summarize the text in 1-3 sentences?

Hi all.

Ever since I've known my closest friend she has been driven and a bit highly strung. However, she has only gotten worse over the years, or at least not better.

She immediately joined a bunch of societies at university and the huge amount of work required for them has caused her to fail many of her subjects, causing great stress.

All of her boyfriends/guys she's seen have been really gross and sleazy except one, and she always has bad breakups, causing stress. By way of example, the last guy she dated was due to go away (permanently) in 3 months. But she still dated him for some fucking reason. I tried to warn her that he was a sleaze, and that he was using her, but she ignored me and then became very angry at *me* when he inevitably broke up with her.

More recently she has finished university, but is now working a shitty  street marketing job that requires 12 hour shifts, often with no breaks. She works 40-50 hours a week.

I have hardly seen her in 2 months and my other friends haven't seen her properly in at least 6. She cancels on every plan she makes with our group at the last possible second due to tiredness. If she does come, she immediately passes out on the couch, doesn't engage with anyone and eventually goes home early.

I don't know what to do. I think she needs serious therapy. I know it might not sound that serious to many of you but she has really changed from her bubbly, energetic old self and I think she's honestly killing herself slowly. It makes me terribly sad and I can't stop worrying about it.

I can't bear the thought of doing nothing. I love her so much and I really want to help her but I'm not sure how to do it.

What can I do?
<bot>: best friend slowly killing herself, can't seem to see it. I don't know how to help and I'm really desperate.
