I feel I am lying to everyone.
What are you doing to lie about?
I'm lying to them that I'm a popular blogger who takes care of a startup
You shouldn't mislead people that way. People aren't going to trust you anymore if you do things like that.
I lied to them, I am not a startup owner nor am I famous.
If you are lying to people about money they could sue you. You should always be honest when dealing with others, they could retaliate.
