<human>: Could you distill the essence of the text into 1-3 sentences?

My gf is great, loyal, sweet, loving and every other adjective but god can she whine.. She constantly feels bad either mentally or physically. She is underweight so she has a food problem. She wants to gain weight so it's not that kind of problem, she even buys those fatty powders with empty calories to get more fat in her. Her stomach is constantly unsettled and always hurts when she doesn't eat enough. Either that or it's some mental problem about nothing.. just random sadness about.. Nothing.. Sometimes it has a topic sometimes it's just her feeling bad but not sure why. She cries 90% of the times we talk on the phone. Thing is I'm not doubting her pain, I've been listening to her and supporting her for 6 months. I shared her pain and wanted to help, but I can't take it all the time anymore.. I have problems myself. I am depressed and feel bad and when I have a great day like today I don't want to get home and get a text telling me to call her because she feels bad and then sit there talking for 1 hour about how she feels bad...

I don't know what to do.. Help
