My advice is to go for whatever you feel like you would enjoy doing. Architecture is not a bad field to get into by any means and it pays well. However, the most important thing to ask yourself is, "Can I see myself doing this and enjoying it in twenty years?" Money is not important at all if you don't like your job, so I say if you like architecture, go for it!
As for your drawing ability, that is something that can be easily improved by just practicing. Even if you don't want to draw, there are many computer programs made for use in designs. Furthermore, remember that in architecture, communication is the important part in drawing rather than creating a piece of art on paper. With practice, I'm sure you'd do fine for any drawing skill that you might need.
