I have no witty title

I am 37, a mom, a wife, a sister, a daughter. I went to college, ran a business for 10 years, started my own company, teach a handle of new workshops every single month, I juggle, I survive. Why is it that sometimes I feel like such a loser? Why do I read about others and wish I could be someone else? Why did I spend so many years so terribly depressed and heartbroken? Why am I so hard on myself.

I'm not feeling particularly depressed or anything. These were the random thoughts going through my head tonight.
