Feeling Insecure

Idk why I'm crying tbh. I feel so insecure with my looks. Idk how I even got a husband. I see people who are beautiful and I just don't feel pretty at all. My employment specialist in this program I'm in told me if I don't fix my looks someone will take my husband from me. Also how she's surprised I even got a husband. Then there's me having trouble getting pregnant so I feel like my body is a failure. I miscarried our only baby. Idk why I just feel so insecure right now....
