On to IVF, I guess 😢

MamaBear813 • Married Dec 2014 • TTC #1 since Nov 2015 • 3 failed IUI's • IVF • FINALLY PREGNANT after IVF #1 🙏🏼🙌🏼👶🏻💙 • Baby boy born July ‘18 💙
After TTC for 1.5 years, 3 failed <a href="https://glowing.com/glow-fertility-program">IUI</a>'s, and lots of meds and shots, our doctor has recommended that we move on to <a href="https://glowing.com/glow-fertility-program">IVF</a>. I am still trying to process this decision. Never in a million years did I expect that this would be our journey to being parents. We wholly believed that we would get pregnant almost immediately once we started trying - I guess everyone does. But it was not to be for us. I was diagnosed with endometriosis and a low ovarian reserve (very low, 0.31ng/ml ☹️)
I am struggling with the fact that my body cannot function the way it was designed to. I feel sad almost all the time because I haven't been able to get pregnant. I (regretfully) feel bitter towards pregnant women and mothers 😞 
I am just incomplete 😞
Any <a href="https://glowing.com/glow-fertility-program">IVF</a> momma's willing to share their story or how you dealt with the emotional journey to motherhood? Any advice would be great as I feel like I am at the end of my rope 😔
