<human>: Can you provide a brief rundown of the text in within 3 sentences?

My S/O for about a year has been going through a very tough time both financially with her family, in school and generally. I've tried to be there for her, comforting her, talking to her and the most I can. But we get into fights almost every day because of her very bad mood. She's constantly angry and sad, which takes its toll on me. I fell in love with her because she constantly were so happy, but that's totally gone. Now she's just a girl who hates everything around her and brings me down with her. Right now we're not talking because I said that my mood and our relationship is depending too much on her mood and that I'm tired of it. Are the feelings I feel wrong, or is it okay to feel this way?
