Sell the car. Pretty much everywhere is accessible through public transport / taxi now.

Is your wife working? Could perhaps talk to your wife whether she wanna start working as well.. dual income helps alot.

If your wife doesnt want, then you just have to suck it up and make do with what you have, be thrifty and spend when you really need it and not when you want it.

your salary is okay considering you started off from a nitec background.

If all else fail, pls go see your MP.
