My girlfriend (20 years old) needs some time apart from our relationship (21 years old) to focus on her mental health and deal with her underlying depression.

About five months ago, I connected with this girl, and we really hit it off. I got her Instagram, and since then, we've been chatting and chatting on the phone every day. We've been together as a couple for three months now, even though we’re in a long-distance relationship—she's in America, and I'm in New Zealand. We have a strong trust between us. However, recently, she started to talk less, and while I understood it might be due to the Christmas and New Year season, it felt a little off. So, I reached out to her last night, and she opened up about how she’s been feeling. She mentioned that she’s going through a tough time and is afraid of slipping back into depression, something she’s experienced before, and it was really bad. She was very open about her feelings, saying that right now, she needs a friend more than a boyfriend. She wants to take some time to focus on herself because she often neglects that. In the past, when she faced similar challenges, she lost a lot of friends and feared losing me as well. That’s when she suggested taking a break from our relationship until she feels ready to reconnect. I assured her that I completely understand and that I’m willing to wait, as she is the only one I want to be with. While I trust her completely, I can't help but feel a bit hurt. I had hoped we could work through this together, but I realize I’m not a therapist, so I’m not sure if that’s the best approach. I would really appreciate any suggestions on how I can express my support and show her that I’ll always be there for her during this time.
