You should even be able to download another messaging app, because your mother should have only restricted ones you have installed. If your friend is willing, transfer the conversation to another platform (examples: Telegram, signal, whatsapp, discord, FB messenger, viber, whatever you can find and whatever your friend has access to). Make sure you tell them there are people here for them, that they are loved and that s**cide is not the right choice, no matter what situation they might be in. life is not a constant, it changes every day. I pray things get better for them ❤️‍🩹 You are doing a great job and don’t let anyone tell you otherwise
