1. narrow the bars for street cred (no one, but no one, runs wide bars on a fixed gear)
2. please do not ride in active traffic without a brake since you said skidding/skipping etc makes you nervous (that is a good reaction to have at first).
3. ride your bike! have fun. it will all come back, and get better every day. I learn something new (subtle) literally every day, have been riding fixed for about 10 months now.
