Have you guys ever felt like you are behind in life?

Have you felt like you’re way behind on life? I feel like my peers are getting married and having children while I’m here in my mid 30s, single, unlucky with dating and I’m just not the woman to have a relationship. My dad said any man that ends up with me will have a good woman. Well the thing is what if a man doesn’t accept my aspergers? I work, I am studying to be a teacher, graduated from college last year, independent and get myself places (take public transportation because I don’t drive) but I’m still working on myself and I’m not girlfriend material. I still live at home. What man wants that?
My former coworkers and friends are mothers. One just had two twin little boys. She has a little girl.
One of my other friends and her husband s expecting a baby girl this year. I mean I am so happy for them but I can’t help that I’m feeling….. jealous. I know it sounds bad but it’s true. I’m so jealous. I don’t think I’ll ever have that experience. I’ve only had one boyfriend in my life when I was about 21/22 years old. I’ve talked to different guys but didn’t work out. I mean I do have some childhood friends that don’t have kids but two of them I know are in relationships.

Maybe a sign is telling me to just go after love but I feel like I have a wall surrounded in my heart. We went through a tragic death of our mother (stage 4 cancer, death was expected) last year and I need to get some grief counseling before I get myself to date again. People don’t understand I need time.
