SLOW DOWN .... RELAX.
The 'processing' time is from the date of the interview ... which appears to only be around 90 days.
You didn't tell us your nationality ... this makes a difference when they are conducting background checks.
Also, you didn't tell us how quickly you filed the AOS after entering the US, nor what kind of visa was used.
If you entered on visa waiver and/or used a B-2 and filed within 90 days of arrival ... that can cause delays ... they will be contacting the US Consul/CBP to see if you could have provided false information as to your intentions.
Wait for your lawyer to come back.
Don't wast time on a CongressPerson ... they never provide any valuable assistance in this type of case ... all they do is write letters.
