Rooster Female born Feb19/1969 My business and money

I am working now on my own business. I see many obstacles but I keep going. At the same moment I have a job which allows me to pay off my own bills and rent but it doesn't allow me to focus 100% on my business. Should I take a risk and quit my job now and to focus totally on my own company? This is very risky because I will need to take some money from my credit cards. Should I quit my job and concentrate 100% on my invention? Please help me in taking this decision ! I have a huge fear but something insight of me tells me that I should finally change my life. Last 4 years it was disaster in every area of life: toxic relationship, depts, problems and really very hard job under my qualification - just to pay these debts and keep going. Please help me. I will be so grateful.
