Craving chicken, haven’t eaten it for 20 years, HELP

I have been vegetarian since age 12 and started eating ethically raised fish a few years ago, about twice a month. Usually the thought of eating any meat makes me so grossed out. But...

I cannot stop thinking about eating chicken. This craving has lasted for weeks and getting so bad that today I almost cried. I don’t want healthy chicken either, I want fried chicken, chicken nuggets, chik fil A (which I have never even HAD before in my LIFE!!! Wtf baby!!) I am worried that this is my body showing me it needs protein or iron, and I have such horrible morning sickness I’ve been living on carbs, so maybe it is from that?

Mostly worried if I eat chicken I will get sick since I haven’t had it for so long. Also I will probably cry while I eat it because I will feel so guilty. Arghhhhh. Send help and chicken.
