I can see that you're writing on behalf of your friend. It reflects on your care for her. You've mentioned about change in her emotional state. Although it is difficult to conclusively say what may have led to this, it will be helpful if you try to strike a conversation with her. Sometimes, talking to a loved one may not resolve our problems directly, but can help us feel calmer and supported. If your emotional capacity allows you, I'll encourage you to provide her this support by listening to her. You can surely encourage her to connect with a counselor, where she will receive a safe and non-judgemental space to discuss her concerns. Oftentimes we bottle up our emotions so that we don't end up overburdening our friends and family. I hope the reassurance she receives from you will encourage her to seek support. I'd also insist you to be mindful of your own emotions during this. It's certainly not easy to see our dear ones experience a difficult time. I hope this gives you some clarity.

I can understand. She might be having a some stress or anxiety.. althaf any Depressive state or in OCD similar symptoms may happen ..so just need little bit more history before blindly do may kind of assumption regarding diagnosis ..connect if needed and u feel like
