I really need to connect to her, we have so much things in common we haven’t talked for 7 months is there a way to send message to her with email or something please 🙁 our friendship is so strong i don’t want to lose her. If i give you the channel can you send a video link to her and me so we can keep in touch in the comments or send a mail to her please ? If u do this u are awesome :)This is her channel: https://youtube.com/channel/UCYxG5fUQC6Y_CIr5FcKwbeQ
If you are such good friends then you should just be able to contact her and ask her for the channel link. There is no way to message anyone on YT anymore, and even when there was you would need to know their channel.
