Hi ankietyjoe - thank you for your message. Really appreciate it. I will try the salt water. I just find it shocking that anxiety can make you sooooo exhausted, alongside all the other ways it can make you feel. I keep thinking something else must be wrong. I know I just need to calm down and get a good sleep, which I haven’t done for a while. Such a vicious cycle! I feel like I have a cold but there’s no cold! :( thank you for your response though!
