Hi there ~
You have all valid questions. You need to do some research on your own to feel empowered. I suggest the National Institute of Mental Health (NIMH) website for depression
and the weblink is provided below:
My thought is that after you read through the website (which is authentic) please visit with a psychiatrist
as I do feel like you at least need to speak to one to help yourself with therapy if you are not a big fan of medications. However medications along with therapy have the greatest benefit in depression and related disorders.
I hope this helps.
Take care and have a lovely day!
