I do better on my own, however, don't let the cold temps get you down.
I went and ran outside yesterday, despite the fact it was only 9 degrees outside and we had a wind chill of -10.
I dressed in a layer of running tights, lined wind pants, tank top, long sleeved shirt, hoodie, and face mask type stocking hat, mittens and my running shoes, expect for my very tippy toes, I was soon sweating.
I was a bit leary about this, but I needed to do it, so I sucked it up and went. My only mistake, is I should have went into the wind on my way out, not my way back.
On another note, I hadn't ridden a bike in years, I remembered, riding in a straight line, ok, turning, not so much, lol.
Hang in there! It all gets easier with time and practice!
