I'm lost

I dont know what is going on with my long distance relationship. This last week I felt like she was getting bored of me, since she was replying to my messages a bit colder, but we were still chatting and sending audios to eachother, but suddenly she just blocked me from every social media. She didn't even text me why she would do that.

I suppose that she just wants her space, but I have no clue. She has told me that is quite difficult for her to express her feelings or that she doesnt know what is she feeling, and I have said her that I will be there waiting for her when she feels ready, I will be there to listen all she have to say.

But now that she blocked me from everywhere, I don't know what to do, because I really miss her and I would like to send her a mail or something. It's like I feel sad but I just feel lost, I dont know how to explain that to be honest 😔, I just want to keep in contact with her. But actually, I don't if it's better to let her go or try to take her back 😔. I just feel lost and disoriented, maybe I should just wait, I have no idea what to do since is my first relationship and I really love her, and want to take care of her.
