Hi Magpie Mia,
Welcome to Beyond Blue. And well done for reaching out.
One of the things a very wise friend once said to me was to look at what IS, rather than 'what it's. N other words, keep your mind in the moment by focusing on what you can see, hear, taste, smell and feel right now.
For example, I had terrible anxiety when I was young due to being in a bushfire, and for years afterwards I could be triggered by a sunset. It wasn't until I was taught to focus on what was real, rather than imagined - IE; no visual smoke in a sunset, no smell of smoke, and no flames, no alarms going off etc - that I began to be able to calm myself and bring my thinking back to right now, rather than back then or the 'what ifs'.
Also, there are herbal supplements available for help with sleep. Maybe you could give those a try for a month or so?
Please note that I am no professional, just a fellow human who has experienced anxiety.
There may also be a counseling service available through your local community health Centre.
In the meantime, the BB community is here for you and with you for as much or as little as you want.
Take care. Hope that helps a little. Xo
