Hello! I need more advice and I promise (or will try) not to bother you all again....well at least for a while!

Seriously, I really appreciate your help.
Here it is. I am trusting that someone will help me with his/her wisdom and experience.
I am in a single female in my late 40s. Last year I opened a Roth IRA. I contribute on my own without an employer contribution. I gross 65K a year and have two teen-aged dependents. I am now wondering if I made the right decision of going with a Roth rather than a traditional IRA. I will be in a lower tax bracket after retirement and my 401K and savings is all that I will have to live on. My goal is not to touch this money until retirement at 65?, but if life throws me some lemons I may have to.
Do you think I should now go with a tradional IRA or a Roth or maybe a bit of both? I plan to put the maxium in each year.
Any thoughts or ideas for me? THANK YOU ALL! I really really appreciate your help!
