All-round damage, self-indebted, doesn’t know what to do!

Hi Community, I have a completely new problem for me, no previous experience and don’t know any more. So now good advice is expensive. Only a week before, I had the timing belt, at Citroen, done with everything pipapo and pressed off almost 650 euros. What do I get now, if I enter the 4 weeks valid offer of the insurance over 1710,00 euros, effectively out? What do I get if I keep the cart and let it do nothing? What would you do, what would be more profitable? If it does not work, what would you do? I have to invest minimum in axle measurement, new tires, new shock absorbers, rubber bearings, because the rear axle is poltert, but the cart does not go anywhere when I release the steering wheel at seventy and fully tap the brake (which is already great).
