I have been suffering with anxiety for the last 4 or so months. The way I have been able to mostly overcome it is by:
Limiting the times I visit this forum, I limit the times I check the news, I try to meditate 5 minutes every day, I keep a journal of the things I am grateful for, and I try to stay out of my head as much as possible by doing active things. For sleeping, I drank chamomile tea.
I have heard that you can never be cured from anxiety, but that you can manage it. I have heard from youtube videos that a lot of people have been successful by inviting and accepting anxiety when they feel it coming and that is what I am currently working on. It is harder than what it appears.
