That i did this in the shower?

So I've always had this fear to poop in the toilet, since elementary school and through out most of High School. However, I think I have now gotten over the fear of pooping in the toilet, but about a year ago I had to go really bad and I just couldn't do it in the toilet. So, instead while in the shower I decided to let it all out in the tub. Some of it went down the drain and the rest I flushed down the toilet. It happened a few times and then never again. I've done other things to avoid using the toilet, but doing it in the tub really freaked me out. My family found out and didn't say much about it. It was really embarrassed because at the time I was 17 years old and afraid to use the toilet. But I just want to know IIN?!
