Adjustment of Status - I-485

Hi all, I am new to this site but really seeking some advice.
I filed for the I-485 in Columbus O h almost 1 year ago. I was petitioned by my husband, whom I had met in college (we had both recently graduated). Previously I had DACA since I entered the country when i was very young (although I hadn't renewed it since high school) When we were brought in for the interview, I got the sense that the official didn't really question the legitimacy of our relationship at all since she had us interview together in the same room (maybe this is more common than i thought idk) We had tons and tons of pictures and the minimal financial documents one has in their early twenties. Everything was going well until the official started directing her questions towards me. The usual stuff, have you committed genocide torture etc. and I was just sort of dismissively answering no. Then I was asked if I'd ever pretended to be a citizen. I said no but the official stopped me and asked if I was sure. I've been in this country for 17 years, and when I was a kid I went through a rough time accepting the fact that my family was status-less and undocumented so I sometimes lied to other kids and said Id been born in America. I couldn't really remember specifics and I figured maybe she was asking because most people answered yes for that question, especially if they'd been in the country a while. So I changed my answer. I said something like "well sure, maybe, i don't know" The official of course started pressing me on details and I became very anxious. I could feel everyone staring at me and I became very uncomfortable. She asked if I'd ever put that I was a citizen on an application, and in that moment my mind was utterl y blank. I said I wasn't sure. And that was it. The interview finished up but I could tell the entire mood in the interview room had shifted. I wasn't entirely shocked when I received a request for more evidence. The request asked me for i-9s from every job I worked in the US. I was devastated.
I had a hard time retrieving an i-9 for the only job I'd ever really had to fill one out for but when I finally did I hadn't lied about my status. Other jobs I'd worked were under the table and I was able to get sworn affidavits from my former manager and a co-worker stating that they had never asked for my status and that I had been very upfront about everything. I also wrote a declaration explaining why I answered the way I did, stating I had gotten very nervous and confused. I considered adding that I suffer from anxiety and was overthinking but I was undiagnosed at the time and couldn't provide any documentation. Could I make note of this now and send evidence since I can now prove my diagnosis?
 Anyway I sent it all in and its now been almost a year and I haven't heard anything. I got a work permit for a year but that was an application we filed separately. I've sent in different requests to know whats going on with the case and it always says its within normal processing time. No one has been assigned to review the case yet from what I can see and I am growing desperate and worried. Its hard to prove a negative. I don't know what else I can do but if anyone has any advice from me I would love to hear it. I don't know what the chances of me getting a good response are at this point. I know its my own fault but still. It sucks knowing I messed everything up. I really need to visit my grandma who is very old and frail and I fear that I may not have a lot of time left. Should I apply for Daca and apply for permission to leave the country? I'm so tired of this all hanging over my head.
If anyone has any advice or anything to share I'd love to hear it. Sorry for venting. Thanks everyone.
