I agree with the above users.
If you continue knitting as it is now, you'll never wear it.
I would just start over 'after' doing a gauge in the 2x2 rib so that you can do the correct size needed for you.
(Also, instead of ripping the work you've done already, there is a thread on here on how to just roll the piece you wanted to frog, and knit from it. This causes less wear & tear on your yarns as they don't get pulled and stretched when being re-wrapped into a ball - you just knit of the old project)
