Hi The Worrier,
Thanks for sharing your story with us and welcome to the community here. There are many parts to this forum, including a Social Zone if you want some more light hearted interaction with people here.
Sorry to read about your Dad, your anxiety and how it is making you feel both emotionally and physically.
The Beyond Blue website has some information on Anxiety that you may find useful.
All through your life's journey, you will find people that do not understand mental health issues, and that is okay. I experience a few different conditions and don't understand them myself!
Have you found anything that helps you reduce the feelings of your anxiety, or that helps you to recover a little quicker sometimes?
I think rationality can sometimes fly out the window when we are experiencing anxiety, stress and depression. I know strategies that will help me, but in that anxious moment I forget and may be too overwhelmed too quickly.
Please know that you are more than welcome to express yourself here. This is a safe and caring place to do so.
You may also like to contact the Beyond Blue support people for some ideas on how to cope, or for them to just listen to you on a bad day. You mentioned you don't like to talk about it much.
Beyond Blue also have a chat on-line service from 3.00 p.m to 12 a.m. 7 days a week which may be beneficial if you don't like talking.
Hope you find some solutions, and "chatting" here helps, cheers from Dools
