I\[25\]  have an 8 months of relationship going on with this girl\[22\]. We had  some bad times but overall everything was good until last couple weeks.  She is having a real bad time recently. For example:

\-She's in her  senior year(in the best university of country) and struggling with both  classes and especially with her dorm conditions and trying to find an  apartment elsewhere. 

\-She was really into sports but she is injured for  months and it's depressing her to not being able to even run. 

\-Some  family problems I'm not much informed about 

\-She doesn't have any close  friends right now

And for some  more reasons she is constantly telling me how much she hates herself and  thinks about killing herself. Im trying to consolidate her everyday but  can't get her to accept how good of a life she has. Sometimes she gets  angry if I tell her she is actually doing good in life and shouldn't  complain this much. But she actually doing good and I can't understand  how she gets this much depressed.

She  is seeing a therapist for 3 years but she doesn't want to tell these  suicidal thoughts bc she doesn't want to use antidepressants.

I  really loved her and don't want anything bad happens to her. But after  what she said last night I'm not sure if I can continue this  relationship or if I can help her some way. But even just for the sake  of good times I think I should do something.

What  I have in mind rn is. Try to reach to her therapist (without telling  her bc she would never let me) explain the situation and ask what should  I do? 

I think I should also mention that at one message she said "why do you keep living, why don't we both die?"

Tldr:  Gf is going through rough times and is suicidal now, and not telling  this to her therapist so she won't use pills. What to do now?
