Hi guys,
I need your advice. Me and my gf broke up a few weeks ago because we had different visions of our future. But after we talked about it again a week later we both decided that we dont want to throw away our relationship so easily cause we both agree that it is/was something really special. 
Anyways she didnt want to get back together because she said she wouldnt recognize her self right now and that she would need time to find out what was going on. We decided to stay in touch and to see where it leads. I did a lot for us and tried to get our shit together she just agreed but in a emotionless kind of way. But just one day after this conversation she did something that made me angry and I said that I'm not sure if it makes sense to go on that way we discussed just because I wanted to hear a reaction from her something like that she is sorry or that she doesnt want to lose me but there was just nothing. As a result we didnt talk to each other a few days. Then we met to give us things back we had from each other. She asked how I was and that I'm not irrelevant for her. I asked if shed have something else to say but she said no and I asked her to go. I didnt want her to leave but I just wanted a reaction or that she wouldnt leave but she did.

Last night we talked again on the phone because I once again tried to contact her nicely and offered to drive to her to talk even though she made me angry a few times. But she did not want me to. She told me again she wouldnt know who she currently is and she would feel like ice because she couldnt feel anything kind of. That she would sleep bad, that she couldnt concentrate and messed some things up at work and that she would feel exhausted and that she would need time to figure out what was happening. She didnt even contact her family members even though shes always been a family person.
All this happend all of a sudden and I'm not sure how I should behave now. Its been over 6 weeks. At first I was really upset of the way she treated me but now I'm just worried that she might have depression. So I decided to swallow my anger and try to help her.

What do you guy think could this be the beginning of a depression?
What is the right way for me to behave to help her?

Thank you for reading through all of this. If you are suffering from depression dont give up and keep fighting you are all wonderful people and I know there are things that are worth fighting for. I suffered from bad anxiety myself and wish you all the best.
