Impatient in the worst way

I had no clue how difficult this would be. Now I am deep into the stress. It physically hurts. I am trying to start a business with very little help and almost no knowledge of what it is I'm supposed to be doing. I want to do this the way I know I can succeed. I want to be given a list, a formula, the answers. I want to be a good student and apply the things I've learned. Not gonna happen. This is a trial and error, sink or swim situation. This is the very type of stress that makes me run. And yet I'm stuck. I can't run, too much has been invested in me and so I'm forced to figure it out. I have hope that it will get easier over time but at this moment I feel extremely fragile. I feel as though I might break.
I find myself wishing for the good ol' days when all I had to worry about was changing diapers, giving baths and making dinner. Isn't it ironic.
Not only am I working hard to build a franchise, I'm taking two online summer classes which means 16 weeks worth of work in 8! And they aren't breezy subjects math and nutrition-which is most definitely full blown science at the cellular level.
I really miss my family and the carefree summer days I've taken for granted my entire life! I don't know what to do. I've started taking my medication again to take the edge off of my anxiety. The feeling of always having more to do, the worry that I'm making big mistakes, the fear of the unknown all got to be too heavy on my own. I've also been throwing prayers up to heaven more often. I'm more  afraid than I've ever been.
So what do I do when I feel so trapped and on the verge of tears? I count my blessings. For some reason this little exercise in gratitude has such power. When I begin to list the good things I begin to see how out of balance my worries are. I'm actually having great success with my new job I just wasn't prepared or trained properly and feel out of my element, I have good grades in my classes I just don't want to do the work, I have supportive friends and family cheering me on, I'm glad I'm growing and of course it wouldn't come without sacrifice. Nothing is wrong with my life I've just programmed myself to believe if something is uncomfortable I shouldn't have to do it!
All I can do is take one day at a time,  try my best and hope my best is good enough.
