Relationship advice needed.?

i have been stressed with money issues lately, and last night i was feeling down, so every little joke that my girlfriend said to me i took seriously, even though i know she would never want to make me feel bad. when we got home, she had been feeling sick, so i was putting her to bed before i moved the car, i asked her if she was done being a jerk. stupid, i know. then she asked what i was talking about, and i told her that some times the way she says things makes me feel stupid. and she felt so bad. i went and moved the car, and came back and told her i was sorry, but she still doesn't understand why i said that, and i think it was just the stress. i am just wondering how i could explain it and make it up to her?Relationship advice needed.?
When she comes home from work....light some candles...cook her dinner (or get her favourite chinese takeaway) and have dinner and Just tell her your feeling stressed lately and your sorry...
