It helps to have a good support network. Including people who have started businesses would be great to have, if you have access to any. Friends, Your Spouse, your clergy member are also good candidates. In some ways it can be even better if they are not directly involved in your business that way they can provide some distance. The key things are first of all they need to be people you can trust, and confide in. Second they must be willing and have time to provide a Limited amount of ongoing support.

If your business has or can assemble an advisory board, they can also be helpful here. The difference is an advisory board can have a bit of a conflict of interest of sorts advising you on the business, and the emotional ups and downs you are experiencing at the same time. They also cannot provide the prospective of distance as the other people I mentioned above.
