Omg you could be me!! Well me 10-15 years ago. We got into so much debt because i wasnt working. DD at home, no family support for me to go to work and like you, anxiety.
Firstly, where does your dh think these school hours/term time only jobs are? They are like hens teeth.
Are you claiming any benefits? Our biggest mistake was not realising we were entitled to tax credits. Instead we relied on credit cards and it all spiralled. So check this out you might be entitled to something - this brings with it free prescriptions, dental care etc.
Also what debts do you have? Would you consider a debt management company? Only consider this if your credit is already screwed. We are paying off £15k of debt £120 a month, interest frozen and we dont really notice it. It does put you in default but we already were so it has only improved things. Another 4 years and we'll have cleared it.
Im working now bit didnt work until dd was 10 and despite dp being self employed we struggle hugely during school holidays. Childcare for older ones in the holidays is a nightmare.
What work did you do before?
I took a cleaning job in my old place of work. In the evenings and it was a killer but it was a foot in the door. Im retraining now doing my dream job but in acompletely different field to what im qualified in.
I cant imagine being able to do that with a young baby though.
I think your dh is being unrealistic. Yes it would be lovely for you to get part time work but it might not be financially viable and your mental health is important.
PM me if you want any more advice re the debt. I sadly have that t shirt in many sizes
