you say you opened a business 7 months ago and that seems to be the major focus of your anxiety?
that, unfortunately, is the exact nature of owning a business.
you get the opportunity to possibly reap unlimited income, unlike a job where you work for someone else, but you take on all the responsibility of running it in the meantime.
i've owned my business for 25 years...it takes quite a while to build it up and relieve the anxiety you get in the beginning. I had a lot of tough times with no money but if you stick with it, things work out.
the only solution is to work hard and make it a success.
