Welcome Jeni. I think it's pretty normal to feel out of sorts for the first several weeks of being sober, I know it definitely was for me. Later on in my sobriety I found out that I had anxiety and OCD, most likely had it all along and just never noticed because of the alcohol. Give it some time and if it doesn't improve consider seeing a doctor or a counselor.
Another thing to keep an eye on is caffeine - I became much more sensitive to it after being sober, I have no idea why, but I cut way back on that and it was very helpful.
