In business, well in life period, we have to stop taking things so personal. Stop making life altering decisions based on our feelings. I think a lot of times we use how we feel as an excuse to do or not do something. It is a big hinderance. Bigger than any let down or disappointment. Your feelings will tell you can not start a new business but the fact is you can!
I know starting a business can be overwhelming. You don't know where to start. You don't know how much money you need to begin. The only thing you know is that you have a product or service you want people to receive. That's honestly all you need. You can do whatever you think you can do and what you can't do you can pay someone to do it for you. Don't let your feelings keep you from success. They are not facts!
