Abortion, Adoption (if you're anti abortion bye)

I posted the past couple days looking for help.

My world was turned upside down finding out my boyfriend of many years had been cheating and I'm not staying suddenly made having this second baby seem horrible.

People keep saying (I would never give up my baby cause of a guy) well I don't want to raise 2 kids alone I desperately just want an abortion but I've carried this baby all the way into my second trimester and I would feel so embarrassed that my friends would know I did this. I don't want to pregnant anymore. I just don't know what to do and I have to figure it out really soon because I'm creeping up on a deadline for abortion. I'm worried I will regret an adoption more

I was told to post in abortion support group on here but received almost no responses.

I am posting again because I have an abortion scheduled for tomorrow afternoon, and was hoping for more insight sorry if is annoying I'm really struggling with this decision.
