Just wear the diapers and do your usual routine at work. You have to allow yourself a little time to get used to wearing them. The longer you wear, the easier it will become.
You keep overthinking this whole thing and that just gets you all fracked up inside and you just freak out.
Stop.
Take a few deep breaths--in...out...in...out...in...out...
Is that better?
I will repeat some of my old advice again:
Unless you are being obvious or don't take minimal care--tuck in a shirt, wear underwear over the diaper or a onesie to help concealment--no one is going to notice or even care. People just don't pay that much attention to things around them. Their apathy is your #1 camouflage.
Being so stressed out is going to draw attention so you need to work on some relaxation techniques.
Wearing regularly will do a lot to reduce the fear while wearing. It normalizes the whole situation for you and it becomes no big deal that you are wearing. Now I've been 24/7 for nearly a year and wearing is quite normal for me. I still enjoy wearing--most of the time, but we all have off days--and while the novelty has worn off, I still get a lot of comfort being padded.
Bub, you need to bite the bullet, quit freaking out, and just go out and wear. The initial fear and adjustment is a pain, but you get over that pretty quickly. Then it will go from something that creates panic to something that creates comfort. With as much stress you are under--from what you've said on here--you need something to comfort you. I know it can be scary going out wearing but I took that step early on and I was wearing horrible pullups.
I had an appointment with my old therapist in a nearby city. I was experimenting with the cheap Walmart pullups at the time and I wore during my half-hour drive into town. I remembered to bring some spares with me. I arrived about an hour early so I walked around downtown, peeing a little at a time into that pullup--and I even changed in a public restroom. Frightening? Yes it was. But nobody gave any sign that anything was amiss. It was pretty liberating to wear in public and I even wore to my appointment. Throughout that whole hour, he didn't even give any sign that he noticed I was padded.
It was liberating. It was nowhere near as bad as I thought it would be. In fact, while I was thinking "Oh Sh*t, I'm wearing a diaper in public!", everything and everyone around me was quite mundane. No one knew or even cared. This happened last summer so the streets were fairly crowded and there were plenty of people out there to potentially notice me, but I had taken reasonable precautions and it was uneventful--other than the joy of wearing in public like that for the first time.
