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

Hi, 

I'll try keep this short and sweet because if i don't i'll make it long and complicated and nobody needs that! Basically me and my ex broke up last summer due to distance and she wasn't coping with it well. Since then we've back in the same city for a few months and she's noticeably incredibly depressed.. She can't sleep anymore till around 4am despite going to bed early. 

She rings me whenever she's drunk in tears and absolutely pieces apologising for 'What she's done to me' and she tells me how alone she is.. I tell her i'll always be there for her and all this (Which is true) and i'll go see her and make sure she's okay. She admits to only being happy when i spend time with her and she doesn't know what to do. 

I cant cope with these 4am phonecalls. I feel guilty despite not being able to do anything because i'm currently in another city! I can't go make things better and i'm finally starting to move on from her and knowing she needs me to make her feel better is tearing me apart with guilt. 

I'm thinking about calling either her mum or sister and explaining to them how messed up and depressed she's become recently and asking them to see how she's feeling as my ex bottles EVERYTHING up to everyone except me. Either that or surprise her by bringing her friends from back home to visit her? Although i do this i'm afraid i'm breaking her trust but i don't want her to end up doing something severely stupid.

Help!
<bot>: Ex-Girlfriend is severely depressed, only turns to me and I still can't help! Worried she will do something stupid soon, what do i do?
