Anybody else ever feel like this??

Ok, I have been ttc for the last 2.5 years. I was placed on Clomid by my OB/GYN. We tried a few rounds last spring/summer and my body didn't take well to it. For my mental health sake we decided to take a few months off meds to give my body/mind/soul a break. We went to a fertility specialist in January and was placed on Femara. Today I got a call from my very BEST FRIEND in the whole world, she informed me that she was pregnant after taking out her iud within the last 4 months. I am having the most mixed emotions that I never thought I would. I feel so bad that I am so jealous. Don't get me wrong, I am over the moon or them but I also feeling intense sadness. I don't know what to make of these emotions or how to handle them. Words of encouragement or strength need ladies.
