Locked in

So, I have this thing I do where I lock in on something and I obsess about it until I'm miserable.
Right now, it's a car. Basically I want a very specific car, but the new one is coming out, and they don't have it in stock except for one but they're giving me a GREAT price because they're trying to move inventory, but I need to sell my car and my mom has the title, and I'm on it but it may say AND 'me' not OR 'me' which would me she has to be PRESENT for me to sell the thing, but I don't even know if I can get a good price for the thing, and I feel stuck and................................................. I can't stop trying to figure out ways around it.

I know the fair value for this car, I know the depreciation, I know that my loan will never be under water if I get X amount of trade-in (or down payment). I KNOW EVERYTHING.
And I'm still trying to get more info. I need it all done instantly, not 3 days from now.
