Given your statement above, there's really no question beyond this point. You promised riches and success to family and friends and it is not currently looking like you will do that, and their message is "stop please before its all gone". Do so.
If you still have money and it is from family and friends then stop right now - on Monday (tomorrow) and give back all that you can. If you burn the rest of that cash then for the rest of your life those relationships will exist for you only in the light of that money. It would be different if the money you had was from an angel or VC who are taking calculated risks.
Your family and friends relationships are worth infinitely more than any startup.
You should instantly kill all business costs, go get a job, and continue marketing what you have built on the side.
