I just landed and I tried launching off. Didn't work, I don't have enough fuel to make an orbit or escape Venus gravitational force. What do I do?

I have no DLC and no mod, pure vanilla. I'm proud of this creation.

I just landed, broke everything all the way. And I returned to earth

I built mini station at low orbit of earth to refill a small craft, I was thinking about docking the fuel tank with the small craft and go to Mars. Anything I should be noted about?
