Hi Norma (I like your nickname lol),
It's clichéd but if they left because of your anxiety, they probably aren't worth having anyway. You wouldn't want to get married and have kids with someone who doesn't accept you. I left my husband when my daughter was quite young because he not only made my anxiety worse, he wasn't very accepting of it.
You've got plenty of time to find someone. Try not to compare yourself to others, even though it's hard. Living a "normal" life isn't the be all and end all anyway.
Take care
