What am I missing? Why can't I stop buying?

I really want to embrace nobuy, with the eventual goal of a 6 month streak. So I want to go about this strategically and with a plan. I'm posting this hoping experts here will chime in to help me understand the why I keep buying and also tips to get started strong and without relapses.

***Sidenote: I'm not counting experiences like family dining out or museums, etc. as no buy

Motivation for nobuy:

• 1. Save money for emergency fund
• 2. it's really important to my spouse (this is the biggest pain point)

What I've done already:

• Paid off all CC debt - major motivation to keep it that way
• Canceled most subscriptions
  • Still have Netflix (cheapest) and Peacock: Rationale is I need this while I'm working since I WFH and ads distract me from my work
  • Still have Text Blaze because cuts so many work tasks in 1/2
• Started journaling (I read that helped someone)
• Got my Libby app going - no new books in months

Weaknesses:

• Amazon: I don't get it's chokehold on me, I literally can't explain it
• Things for my kid: I just can't help thinking this next thing I buy will be the thing that teaches them, or entertains them, etc.
• "Health": Arguable because I have no conditions. It's mostly supplements that might help. I don't end up drinking them and have tons sitting on my desk
• Social Media: I'm a doomscroller and those darn targeted ads get me every time
• Starbucks: Can't resist - did anyone beat this one?
• Skincare: I've been self-concious about this lately and have spent money on devices and serums promising to reverse time

Backstory:

• I come from poverty and sometimes want for things I didn't get in childhood: pens, notebooks, stickers, toys for my kid, etc.
• I end up spending convenience taxes: Things/subscriptions etc that promise shortcuts. Example: TextBlaze for work
• I feel like I should "treat" myself to things, like I deserve these things: Starbucks, skincare, vitamins, etc. Don't know any nobuy ways to treat myself.
