I met a business owner yesterday who seemed ground down by a series of events that could happen to anyone, one at a time but these have all come at once. Running a business is a lonely career choice. My advice for what it's worth, get networking with other businesses so you can not only grow your business but also get the support of mates when you need it. Sure you will meet the odd d*** who only wants to sell to you, (and if I'm honest I made that mistake at first), but if you do it right you will soon find out that you are not alone. Keep the faith and stay on your feet!
