Hi Linda, congrats on the 5 years:) I am now 9 years out, I had the surgery, chemo, rads then also went a trial for herceptin for 1 year...after that no further treatment as I am not hormone positive. You do get used to no more treatment and you will still have your checkups as most trials want to see you for quite some time.
You won't be alone and most people posting on this site will understand how you feel...there is so much we can do ourselves such as being involved, keeping busy, exercising, diet related, relaxation and the list goes on...
Good luck x Sharon
