Hi Tracey it does become overwhelming you are getting help with counseling and that is a great start.
I found the beginning really difficult but you need to take it one day at a time. I'm now getting to the end of my trip and you need to know that there is a light at the end of the tunnell. I was diagnised in Febuary 2014 and have just finished my herceptin and believe me there were times when I thought I would not get to the end but here Iam getting ready for a holiday to celabrate the end of treatment. This site has been great I always feel I'm not alone and there is someone out there that does understand my feelings of very high and very low. Take care of yourself and keep asking for helpx
