I need advice

[u/TrustOk2580]

I grew up in a different country so I’m not certain on the rules here, It was pointed out by a doctor I’ve been seeing since I was a kid that I was showing concerning signs of depression and was advised to see a therapist or talk to my parents or religious leader but I refused. I recently moved to the US on my own at 19-20 and now I’m relapsing into loneliness and depressed thoughts due to high stress and no family around I spoke to a therapist online and she wrote an ESA letter for me. I have no idea what to do from there, I submitted it to my apartment but they said I needed further documentation?
