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

My girflriend is really often depressed and moody. She has a hard history, and has been trough a lot in her short life. So I have a clue why she is so depressed, and she really has reasons to be. 

 Only thing is, our relationship is pretty new, and as a BF I should be there to comfort her and listen her. I'ts just so hard when she is like 80% of the time depressed and sad. She also gets angry really easily because all of this. How should I cope with this? She has said that it's not good time for her to be in a relationships, cause she has so much own problems but still wants to, cause she loves me. I don't want to always worry about my GF, but I feel like its my job to take care of her. Should I just try to cheer her up? Or give her space and let her open up when the right time comes (if it ever comes). Normally this would be normal(everyone is depressed sometimes ha?) but she is like almost all the time. When I'm not with her, when I'm with her, when we sleep, when we fuck, when we chill. I'ts really hard to see someone so sad, and I cant fully enjoy our relationship. Help
