Morgan & Morgan Asking Me To Sign Limited Release Before Showing Itemized Deductions. What Can I Do? (ga)

I was recently in a car accident where the other driver was deemed at fault by Progressive. I’ve been working with Morgan & Morgan on my settlement, and they sent me a Limited Release for $25,000. This is my first time ever working with a lawyer and getting a settlement.

However, when I asked how much I would actually receive after deductions, my lawyer told me about $7,000. This amount is an estimate, and was estimated only "after all negotiations were settled". I was also told that my emergency room bill was covered by Medicaid entirely. My bill was about $6,200 from the ER, so that wasn't taken out of that $25k. Yet, $18,000 is being taken out, but they refuse to provide an itemized breakdown before I sign the release. They claim the release must be signed first before they can draft the closing statement, which will show the numbers.

I don’t feel comfortable signing without knowing exactly where my money is going. I’ve asked multiple times for a breakdown, and they keep delaying or dodging my request. Can they legally require me to sign before showing me the itemized deductions? What can I do if they continue refusing to provide transparency?

Side note, when the lawyer had told me to give her a call on the phone, she word-for-word said "The reason why I told you to give me a call was so you don't have to keep asking me so many questions because you go back and forth so much, and ask so many questions all the time." I kinda was caught off-guard but not surprised because I felt like I was annoying her, lol.

Would I be able to consult another lawyer at this stage, or am I stuck with Morgan & Morgan? Is $7,000 out of a $25,000 settlement a reasonable payout, or does this sound like excessive deductions?

I don't want to sound like I am ungrateful for this settlement. I am more than grateful, however I am just trying to check my rights before it is too late.

I’m in Georgia and want to make sure I don’t get screwed over. Any advice would be greatly appreciated!
