My bank account is scared to see me

How does one achieve a savings that is more than $20 a week from their whole paycheck when impulse spending is my biggest fall down with adhd. Non adhders never understand and tend to judge me heavily for my spending and all it does is worsen my habit, so please share what has helped you? What have you done that finally beat impulse spending even just a bit to where you could have more savings to put into your savings account? I really need a new bed and things to start my business but my impulse spending on things that I convince myself I need are holding me back from things I direly need🫠
