At a certain point, you go past stepping on toes to plain standing in the way. There is a fine line between not enough and too many people working on something.
Are you me (with a few differences in coping strategies)?
Stress levels certainly impact my urge to spend. Getting outside for a walk or hike is a good distraction.
I use YNAB. I probably look at the budget too much.
I force myself to sell things if it's reasonable to sell them when I want something new. I've sold many phones on Swappa and elsewhere.
I have multiple credit cards and usually pay them off more than once a month. Something about having low balances on cards and in my checking account helps me reduce impulse buying.
I have been trying to redirect the urge to buy something into putting the money into retirement accounts instead. Small purchases of things also helps me to avoid some big purchases.
I buy nice things when I want something in a category. That limits the need to buy an upgrade later.
If you are only applying to jobs that you find through company websites, then I am not surprised by the lack of success in getting responses. I'd suggest trying to go through your network (hopefully you've built up professional relationships along the way) and find a job that hasn't been posted to the internet. I think you'll be more successful if you can get someone to recommend you for a job at their employer.
