My brother, sorry to hear about the problem you are having.
Depression and life crisis afflicts many Muslims in the US. We are living in a very trying time. A hostile or unfriendly society could add weight to those feelings.
Alhamdulilah we do have a solution in our civilization for this kind of problem of the heart.
I would advise you to read more Quran, especially with tafsir.
If you feel you are the kind of person who needs to spend time with people, you can try to sit with Tabligh Jamat and concentrate on Ibadat for an evening.
If you think it may be a result of Jaddu, evil eye, or possession. You can test it the way
@Verve described by reading Quran.
You can also pray 2 rakat nafl and read Istikhara dua afterwards and mention your problem with Allah swt.
Istikhara works for all problems, no matter how big or small.
If you feel like you need professional help, seek out a psychiatrist.
If you need to get away, visit Turkey, Makkah, or Pakistan to get more in touch with your Islamic roots and soil.
Everyone here gave really good advice. In sha Allah, you will get over it soon.
