pain and entrepreneurship

Recently i have come to observe that entrepreneurship is lot more emotional than a job.  On top of  the manic depressive roller coaster of the process of starting up and i have a nagging feeling that i am depressed. I have come to have peace with my family members and their adversarial attitude towards me. But yet the feelings persist of

  • lonliness
  • what if i end up a parent mooching stay at home dead weight
  • self doubt
  • the want to go to  foetal position and cry myself to some sort of emotional relief

In spite of   painting such a gloomy picture, the one thing that keeps me going is the fact that my dream for my product looks into the future and will get me returns in the long run. I am barely productive these days, am i kidding myself into believing that this is way better than a job ?
