Trying to Understand This Situation Better

Hey there. Throwaway account just because I don't want to take the risk of being found out. So I (M25) have been dating my girlfriend (F25) for 10 months now. She and I both live at home with our families, but she has more restrictions on her due to the commitment with her family (actually, she is the oldest of 4 and is out of town on a baseball tournament for the youngest sibling and dad who is the coach). I noticed that this two Saturdays ago, she admitted to me that she has episodes of depression. She isn't taking medicine for it and she tried counseling twice with both times leaving her emotionally raw (one court ordered and the other by choice). I noticed that before that Saturday she told me, she has been pushing me away. For her birthday and weekend she barely talked to me in a group of people and hasn't been texting a lot. She has gotten better about it lately, however, I still feel like she is keeping me at arms length. We were able to hold hands this past Wednesday and talk some, but still not as much. Her friends and other people where there. However, I still suspect her to be depressed. She took me out of her profile picture and we haven't text much today or yesterday. I forgot to mention that when she told me she had episodes of depression, she barely talks to people one on one, or barely at all when she gets this way and that she is better with a group. Here is what I don't get though...how can you say that you aren't great with being with people one on one, but her and one of her best friends have one on one time? They do confide with each other and keep each other accountable when things get dark, but she is in her own way pushing me away I still feel like. I have been good to her. Why push me away? I am wondering why she is pushing me away, but keeping everyone else close? Is this how depression works? Can someone who has been in a relationship or marriage give me some insight on this? By the way, I don't think exactly she wants to break up with me, because I am still listed on her profile as her boyfriend, is excited/showing interest in future plans, and she has been nice to me, but I still feel like she is keeping me at arms length. Thanks! TD;LR: Girlfriend has been pushing me away, I confront her about it, she confesses depression, seems to get better, still not letting me in fully
