Hi Justin,
I think you would be surprised how many people all over the world suffer from what you are describing.
What ends up happening is once the mind is overwhelmed, the body gives up. This leads to panic attacks, stress, problems with weight, blood pressure, etc. The body is literally fighting itself because of the mind!!!
The thing is we all have anxiety, fears, regrets, etc.
These are a normal part of life, however each one of us must find our own way of releasing all of this tension from the mind and the body.
In addition to regular sleep, exercise, diet, and quiet time - one of the things that helps me as an alternative to medicine or counseling is simple breathing techniques. Awareness of the breath is the key to quieting the mind.
There are a few good books on this subject, one of them being Living From the Heart by Puran Bair. Check it out...
You will be alright man. It's good that you are posting here, and seeking solutions with an open mind.
You're not alone
All the best
Daniel
