<human>: My girlfriend has depression and she has had it since way before we got together stemming from her family life mostly.Her mom and sister are emotionally abusive at times and at other times they're ok people. For example, her older sister will do things that make her upset on purpose solely just to make her cry so she can make fun of her and make it a joke. Her mother on the other behaves like a normal mother for the most part, but there are instances where she'll tell my GF that she hates her and she doesn't really say she loves her quite often.  Despite all this simply leaving her family forever just isn't a choice for her. Her father died right after she was born and my GF has always felt a strong sense of responsibility towards her family because her father was a local legend(martyr). For example, she's extremely nervous about leaving home because she loves her mom a LOT despite the abuse, and is afraid of leaving her alone with nobody since her father is dead. 
  
My GF also had traumatic childhood experiences which add to her depression and I've been wondering if there's any thing I can do to help her. I've tried telling her constantly how I feel about her that I think she's amazing and beautiful, but it doesn't help sometimes and I get lost on what to do.  
  
Recently, her sister did the usual thing again messing with her and trying to make her cry. I tried to calm her down so she wouldn't cry and I was a little too lovey and made her cry a little which resulted in her sister calling her disgusting and made her feel worse. I tried to get her to video call me, but her self esteem is just shot right now.   
  
Is there anyway to help my girlfriend with her depression and self-esteem issues because of her family? I've tried looking up advice from other people, but none of it seems to really get through.  I really love my girlfriend and she's an amazing person, but I feel so trapped in trying to help her.

Can you give me a shortened version of the text?
