I have been diagnosed 7 weeks ago and still trying to get my head round it. Definitely good days and bad days. This site is really good, be very careful with what you google. I have been finding the stuff Jack Osborne writes really helpful too.
I am still waiting to start medication but there is things you can do in the meantime like make sure you take vitamin d, look after yourself and mainly be kind to yourself. I have been having regular massages, reflexology and acupuncture too as that seems to help me a lot mentally at the moment x
