As long as you filed your personal taxes during those years that you did not run the business then you should be fine. You would have stated no business income at that time. You shouldn't have too much to keep track of, considering what type of business you run. However, there are many years to complete. I understand you are low on cash but I cannot bid lower than this, considering the workload. I do hope you contact me, if not, Cheers all the same, feel better!
