<human>: Give me the gist of the text in a nutshell

Hey All,
So I'm M21 and she's F19, we've been dating for over a year now and it's always been fine, in fact it still is fine. We've never argued, never had any issues, and pretty much been a great couple.

Recently, in the past 4 months or so she's been suffering from anxiety, depression (Not severe to my knowledge) and well, laziness. 

She see's a Psych once a week and when I ask her how it was she just says "It was good" and tells me what they did but nothing really specific, which is fine, it's her personal doctor. 

The thing that gets me is...I can't help her, she gets upset and sick and it's just scary for me. When I'm with her she's happy and excited, showing no signs of being upset. But when we chat via text or facebook something is wrong/complaining about someone in her family etc.

She's at home a lot, her classes for school are at night and she doesn't go very often, so I suggest she gets a job (I'd like to move out next year hopefully..but now I don't know). She says she's not in any condition to work (although last week she wanted a job) and I say it'll help her get out the house/distract her but she doesn't seem to want to.

I'm getting to the stage where it's bringing me down mentally as well, and I don't know what to do. It's become a "I'm Happy with her" & "She makes me sad when I'm not"

Any Advice? Peck out my brains..
<bot>: girlfriend (19) makes me (21) sad with her sadness when I'm not with her, completely happy when together. Her sadness is pulling me down and it's tough.
