Trinena,
Yes to everyone else's comments, and i will say you are doing WAY better than I did when i started 2 1/2 years ago!

but I'll add one more thing...
Please, whatever you do, don't let other people's impatience cause you to ride faster than you safely can. You do NOT want to be rushing through tricky intersections and narrow areas or speeding down hills just so you don't fall further behind anyone you are riding with. Never ride faster than you feel confident and in control.

Please do NOT compromise your safety in order to please others. TAKE YOUR OWN SWEET TIME when maneuvering through traffic and intersections. Remember you are not a seasoned rider and you will need that extra second or two of safety margin if you find yourself in a dangerous situation.
Your life is worth way more than trying to keep up with other people. You may have to tell them that, too.
