Pissed Off by NSF charges

Shoot! I tried so hard to save every penny I have. I saved every dollars I could. I never eat outside, but bring my own food. I never spend money to go to cinema. I never treat friend to any dinner or lunch or movie. I get as much coupons as I could. I buy cheap items as I could. I earned extra money through Swagbucks. And now what the heck with this Non-sufficient Fees charges that just laid on me! A total of $40! The number might seem small to you, but it is a heck lots for me okay! $40!!!! No kidding. You know I could have had 4 sushi lunch with this money! Damn it. I hate it. Why did I transfer all the money to the interest plus account just to earn more interest. Now the interest I earn is incomparable to this $40 charges! Second time I have been charged with $40! Hate it. I have lost $80 in total for the ridiculous bank fees!
