Texas HoldEm transition from online games to real table games?

I am an online poker player of the last 6 months, I usually play tables $500/1000 where I do pretty good but I've never ever played in a real table until recently where I tried a really small table and I was a mess. Turns out I can't handle small tables in real poker? Is that normal or not? On the other hand I think the fact that I am a woman and I tend to be super cautious at first lets people think I am scared or something? Do you think I should quit playing real tables overall or will I get better as the time goes by? Any tips would be more than welcome.
