Adjustment of Status - I-485

This process have defeated me ... l keep replaying how careful I was. I made sure everything was done I watched videos I double checked I proofread every form n supporting documents to make sure everything went smooth. First issue was USCIS they mailed my bio letter to wrong address I knew something was wrong they kept telling me no when I call finally got someone who actually cared and looked and realized it was an administrative error by there fault .

Next got prepared for my interview everything went well awesome handed in my new medical and all. Just to find out the damn doctor forgot to put something on so after the interview they send me that my form was not completed properly .

Now I've been waiting over 3 months after interview all
Because of third parties error . I just feel like the devil is trying me .over a year in this process and I'm feeling more defeated than ever . I really didn't know I'd be waiting this long after interview . I hate my doctor I hate him
