Am I a girl or a pin cushion?

So I recently have been given a prescription for B12 injections. I need these because I am deficient in that certain vitamin Well I have to give my self these injections and its not a big deal that I have to do this cause I like that stuff. So these injections are supposed to help with my energy levels. I have to do this once a week for a month. I started yesterday and haven't noticed a difference.... SO I guess we will have to wait and see!! Until then have a good happy life!
