I have had anxiety for too long to remember. I take medications as I needed to but that was my situation.
I refused for so long but it go too much. Something I do find that helps me, is magnesium. It helps with sleep and when you have anxiety you hold your muscles differently. It helps with the tension. I would also recommend, if you can afford it, a good quality relaxing massage.
It gives me so much relief, especially from tension in my body. It helps with the exhaustion too.
But definitely talk to your GP and maybe discuss any naturopaths if that is a path you might want to go down.
I am not great with selfcare but just the simple like a beach walk, reading also helps.
But if you need medication give it a go. But really discuss it. My psychiatrist now helps and monitors it with me.
I wish you all the best.
