Adjustment of Status - I-485

Hi guys, my last post was abit brief and thanks to those who sent prayers.
So my husband passed away after my last post last week. It has been so tough. But we still thank God for everything because he loved God and is in a better place with no more pain.

Our lawyer called yesterday to check on my husband and to tell me about our interview for June29th, I told her he had left us... Honestly I didn't pay attention to all the interview related things she was saying till I got her email after the call. She said she doesn't want to move the interview because I want to move to another state to stay with my family at the end of the month, she begged me to try. She said I have to get a joint sponsor now and she has to file that form for me, she said she usually charges extra $500 but she will waive if for me.
Also, I totally forgot about getting my name on utilities because there was no time, everything happened so fast, since November we have been in and out of hospitals and I couldn't bother myself. All I have is our joint account and pictures.
I'm so confused with everything and I'm feeling really depressed right now...
Does anyone know someone that went through this?
