I don't think people that have major depression cant pray it away. People take strength in a higher power and it helps them through tough times knowing life has meaning and thier life has a purpose even though they may not know what it is. I think depression needs more than that. Like help from trained professionals and medication that help relieve some of the symptoms. In my experience depression tends to get worse when gone untreated or Igorned.

Try not to let people get to you so much. If they knew your struggle I am sure thier opinion would change. Don't feel bad for getting help or struggling. Everyone struggles with life one way or another.
