Hi, Swallace13. I acknowledge your feeling of embarrassment. I, too, felt like a bit of a leper, even though the majority of PR was on my torso or legs and could be hidden, there were still times in the gym when wearing sleeveless shirts and anything V-neck, the spots were definitely noticeable that were on my neck, chest, arms. And, def embarrassing, for me, too. And, I'm 52. So, I hear you and wanting to avoid public appearances, as much as possible. I wore turtlenecks when I was out in public. Thankfully, it is winter in Chicago, and I could go about life in turtlenecks and have it covered.
I also acknowledge your frustration. Think all fellow PR sufferers/warriors can relate to both the embarrassment, frustration AND....I'll even add bewilderment, since there isn't a known cause of how we contract it when it's supposedly NOT contagious.
I am on week 7 and my spots have, thankfully, faded, for the most part. Still a bit faint, but faded. Time will tell if they completely disappear. Showering still makes them want to come out of hiding, but nothing like when I showered during the first 3-4 weeks of PR. I share this only to try to encourage you during whatever weeks lay ahead for your healing process. It does get better. I know when I read these threads at the beginning of my PR journey, I thought, how in the WORLD will this ever get better. Just didn't seem like it would as they were so red, angry, overtaking my body. But, after week 3, they started fading. And, each week has gotten better, to where now, in week 7, they are hardly noticeable. Every person is different. Every person's biochemistry is different. Every person's immune system is different. Every person's healing process is different. There are some who are dealing with worse cases than others. Some are dealing with PR that has migrated to mouth and have mouth ulcers. MAN! I thought I had it bad. SO thankful I didn't have it spread to my mouth. Can't cover that up with a turtle neck.
You mentioned that stress could possible be cause of PR. I read that, too, in my frantic internet search when the herald patch originally surfaced. We don't know the cause at this point. I do know that stress is pretty much in everyone's life. BTW, proud of you for working so hard with two jobs AND attending school. Not easy, even for someone younger like you. But, who knows if that is the cause of PR. From what research I have done, there is just not enough science to back anything up as a reasonable cause, let alone a cure. And, since PR is not life threatening, I doubt there will be much effort spent in finding a cure or cause. Like the common cold.
You can ask 10 different PR warriors past/present what worked for them, and each may have different answers. Whatever approach you choose may work for you, it may not. All we can do is share what we did, state what did and didn't seem to work for us and.....it's basically just trial and error, in my opinion. Like you, I first tried hydrocortizone cream on my first herald patch. Didn't do squat. Used it for a week. Still squat. That's when I went to the dermatologist. And, that's when the spots started appearing that felt like hundreds of little pebbles under my skin. Derm instantly diagnosed PR upon examination. She gave me a sample of steroid cream and some kind of gels and said to use that if it was unbearably itchy. It wasn't for me, thankfully. So, I didn't use any of what derm gave me. I bought Aveeno sensitive skin shower gel (fragrance free), used my usual moisturizer and.....didn't really do or take anything different than what I normally would. And, mine eventually faded. Others have used many things, taken supplements. Tanned, etc. I didn't do any of that. My derm said it would take between 6-12 weeks typically to heal. And, she was right. I'm now on week 7 and....I'm pretty much healed. Hopefully.
It's hard to say, do what works for you, as we all are just trying to figure out what works for us individually. Just want to encourage you as much as I can that, based on most other's experience and my experience, that PR does fade. Eventually. Getting to your "eventually" is your own unique journey. Hopefully, you are in a cold climate and can cover up until it goes away. That's what I did. And, every time I saw it in the mirror, I thought, man....this is NEVER going to go away. I'm marked for life. But, it did go away. In the thick of it, it seems like a permanent malady. But, it did fade, eventually. If you can, try to be forward thinking. One week at a time. If you've ever watched the animated story "Finding Dory".....there is a line in there that says "just keep swimming, just keep swimming." You'll get there re healing.
Not to tell you what to do, but sometimes, overdoing it with creams, showers, etc. b/c we are in ambulance mode to try and get it healed quickly, I wonder if that can hinder healing? IDK. Do what you feel is best for you. You are supported. You are understood.
Please take a deep breath. Know it will get better. Post when it does, if you can. It helps keep us in the know. Our own little database of PR sufferers. 
Blessings.
