Everything you are going through is normal and it sounds like you have a good attitude about your quit. That will help a lot.
Remember, smoking does nothing positive for you. Whatever positive things someone sees in smoking is all an illusion.
Smoking does, however, do a whole hell of a lot of negative things for you. You are not giving anything positive up. You are making a huge and great life change by getting the poison of smoking out of your system and out of your life for good.
I'm glad Sazerac posted that thread about Allen Carr. Carr's book helped me out in a huge way and I gained a lot from it. I would strongly suggest reading or listening to it. It really changed my overall mindset about smoking.
Oh, and anytime you need to vent, feel free. That's part of what a support group is about and venting can really help.
You are doing great, Nikki!
