Ron, it could be all of the above. I am with you on being stressed about finances (I'm still paying off the credit card bills from when my dog needed emergency surgery). Being worried about my dog and worried about money have definitely taken a toll on my guts, so something similar could be the case for you.
Were the peas cooked? As you probably know, cooked is often easier to digest than raw. I have found that I can also juice veggies and my guts don't have a problem with that. So either cook or juice your veggies, if you can. Also make sure to remove things like seeds and skins from both fruit and veggies, as seeds & skins can be really hard to digest.
Keeping a food diary might also be helpful for you. I've done that in the past and it was definitely helpful for me.
