How should I negotiate pain and suffering claim??

Hello all, hope you're doing better than I am lol. Yesterday I got into a really bad accident while I was driving, the other person was at fault- sped through a stop sign on a busy road while I had right of way, I didn't see them in time and T-boned them. Everyone is in one piece, but both cars are completely totaled. I was given a severe concussion (among multiples other non-lethal injuries) and don't remember anything, so most of my information is second hand lol

I started the claim with my insurance (Progressive, auto, Colorado) and was writing down the bare minimum costs the other insurance needs to cover. I don't know who it is (or who the people themselves even are) as I have no recollection of the day. The costs currently amount to 4,870.78, not including medical bills (I have not received them yet.) This takes the base value of my vehicle, recent repairs/improvements to my vehicle, and loss wages into account, but I'm not sure how to begin to go about trying to quantify my physical pain or the stress. I am absolutely trying to milk this for all I can- I need the money and now have no way to generate further income. This has never happened to me before, I feel like a fish out of water. Any tips, tricks, experience and advice would be greatly appreciated!! I don't know where to start.

Apologies if this is rambling/repetitive, I'm still recovering from my concussion and still have a rough time being focused/remembering what I was doing
