I can relate to what you're feeling. A few years ago I quit my job and all my campaigns died. I went from $10k a month profit to nothing. Went through about 10 more failed campaigns until I discovered the berries and changed my life. Whatever shit you're feeling, everyone that has "made it" has gone through it. I rather struggle on my own than be someone's bitch for the next 50 years!
This is a good lesson to learn for motivation... you will experience failures, but all it takes is ONE good offer that you can scale and you can literally save up a year or more worth of income in 1-2 months, which takes the edge off your anxiety and allows you to relax and find more campaigns.
Good luck!
