Pregnancy envy?

I don't know if I am a nut bar or if anyone else feels the same way....
​We have been TTC for baby #1 since June 2013 (9months). This week I was diagnosed with endometriosis and at this point we are unsure what stage it is. This may add some significant time to our journey to concieve.
​I find when I am walking in the mall, the grocery store, down the street... Or browsing Facebook... I get insanely jealous when I see pregnant women. It is completely ridiculous and I always feel like such a fool. I can't control it.
​Anyone else?
