TTC while dealing with Jealousy

Hi ladies. My question is more on how to stop being jealous. Basically I've been trying to have a baby with my husband off and on for a little over 2yrs now. I say off and on because we did get pregnant twice within those 2yrs. Both pregnancies ended in a loss 😔. One was a stillbirth and the other was a miscarriage. I've been doing <a href="https://glowing.com/glow-fertility-program">IUI</a> for a few months now and today was my 3rd <a href="https://glowing.com/glow-fertility-program">IUI</a> cycle. With all the poking and testing and trying it's really draining me. And i cant really take any breaks from it because cause me and my hubby have always wanted like 3 kids or so and iam already 37yrs old and hubby is in his mid 40s so we dont have much time. As we are struggling even just to have 1 kid let alone 3. But I just want to know how do you stop being jealous of others? There are several ladies that I know that got married when I got married 2 yrs ago and have babies now or are pregnant. There are even 3 ladies that I know that had a stillbirth back In 2022 when I had a stillbirth and are now holding their rainbow babies and yet iam still trying. I never knew it would take this long to have a baby. And It's even getting to the point that I hate looking at social media because Iam always reminded of other people getting the blessing that I've been praying for for 2yrs now. How do I stop being jealous as iam always wondering when is it going to be my turn and why is my turn taking forever to come. My age doesn't help me to really relax and with all the poking and testing with <a href="https://glowing.com/glow-fertility-program">iui</a> that doesn't help me relax either as iam always wondering when will I finally get pregnant and get my baby. Please help me with some advice or words of encouragement as I really need the motivation right now to keep going. Thanks!
