Founder's life during pre-launch and launch is a survival challenge?))

Ok, when I decided to become a founder of a startup, I could not imagine how hard it would be :) But it's like with parenting I guess: you'll know how hard it is until you try it and actually become a parent. Same with startups... For the last 6 months, I've been building Dokably app. I thought I overcame the main fears when I started product development. No, now during my pre-launch I got to a new level of stress. Now like never I feel the fear of failure. That my startup fails. And I won't be able to implement my vision and idea in life. So each day of the pre-launch week I start with auto-training that everything gonna be all right :) And then, then open up my to-do list and disappear.. into numerous tasks. I guess this week I make 95% of my friends and followers on FB, Linkedin, etc remember me. My best friends will have to sign up for Product Hunt. And my husband.. well, he will just have to survive :) So easy? No. Worth it? Yes. Through this journey, I upgraded myself a lot and developed new skills and qualities. Now I feel I can do anything))) nothing is too hard for me. And how about you?
