Well done for reaching out, on what can be a concerning topic.
I would suggest that if you are concerned, you could talk to your doctor about it, and perhaps also get a mental health plan for some ongoing support.
There are also many apps out there to help you learn relaxation and meditation techniques, if you would like to give those a try?
And of course, Beyond Blue is always here, for as much support as you like.
Take care. I'll be thinking of you. xo
