I was where you're at for awhile,wish I could say "it gets easier", but it really doesn't if IBS is involved. I didn't start wearing "real" (taped-on) diapers until I was changing wet pads and pull-ups every half hour seriously for almost a year. and it wasn't until over a year after I switched before I really acknowledged there was probably no going back.
My biggest hang up before I gave in was with dating because for some reason I felt like pull-ups and especially underwear guards / pads were'nt as "weird" as diapers . After awhile I realized that incontinence is incontinence and how I handled it was more important than trying to minimize it. So accepting constant wetness actually got easier pretty quick once I figured out onesies and boosters etc. and for a year or two I felt dumb for not switching sooner.
But when I started to loose bowel control and needing plastic pants during the day it felt like worse than back to square 1. I wrote in another post about how I was still using pull-ups for exercise (with nothing else) when I had my first "big" public messy accident while out jogging miles away from home. I managed and learned but just know there is definitely a big social/dating difference between urinary incontinence and IBS issues. Even my current partner (who I live with!] doesn't know how often I'm "more than wet."
I'm not sure whats my advice except if you're already having bowel accidents to invest in lots of pairs of good plastic pants. Finally switching to diapers & onesies & eventually even boosters was a quick miracle for giving me back the daily hours I spent dealing with bladder issues, but if I 'd kept trying to maintain some control I probably wouldn't be dealing with random but increasingly frequent messy accidents now. It's hard to explain and still grosses me out if I think too much about it...after a few years I went from finding a toilet immediately/jumping out of bed when I felt an urge to letting it happen and learning to ignore it until my next scheduled change
tl,dr : I sometimes wonder if changing/explaining constant bathroom trips and 10+ wet pull-ups and pads every day while trying to get most of it into the toilet would have been easier than a changing bag and 3-5 per / day wet ( sometimes messy) diapers and also now feeling like I always have to wear plastic pants just in case :/
