It’s good that you realize you are over spending on groceries ! It shocked me too way back when I saved my receipts and saw it!! Fantastic your working on changing food spending.
I thought you had bought the DBT book Nammu is talking about ?? Why would you wait for a new book in May ?? They have DBT and anxiety workbooks books cheap. Your just making an excuse to hold off buying them. You live in a home where your husband and son both have there own mental illness . You would be showing them you are being proactive in using them. Don’t make up illogical excuses. Just order them it’s the first of the month, adjust the rest of your month budget wise to allow for them.
Learning Spanish sounds fun. If your husband is sleeping a lot do it while he sleeps, again your finding excuses. That’s a lot of people default reaction...but that can be changed .
Stop making excuses you and only you can take steps to improve your quality of life.
I just checked on Amazon they have both books starting at 12.99 and up. You can afford them.. it’s just a decision where to put money you’d blow anyway into something truly helpful.
Get made at your current mental state , demand better for yourself
