Hi @kmakm
it is quite normal to feel flat and sad when you come up to your last chemo it is a signalling of our emotions that we have held together to get us through chemo ...
I believe the crying is a process that we go through at this time.... YES you always have permission to duck out mid afternoon for a rest.... When they arrive explain that Chemo means you need an afternoon nap.... So you will be going to lay down for a time in the afternoon....
Have you seen a psychologist ? you are entitled under the Mental health plan to see one under medicare.... Ask either your Onco or GP to give you a Mental health Plan (chronic disease) I waited for about a Year after chemo before I saw someone wrong choice it then took a longer time for me to work through all the emotions I had pushed down going through treatment.
There are a couple of things that helped me ... I do a relaxation mediation by Petrea King that has got me into a good sleep pattern I have it on my Ipod and listen with headphones and drift into sleep while it plays I normally remove headphones and drop to floor and then go into a deep sleep... you can get Mediation CDs at most local libraries or you could download a YouTube version on one....
another good one is Letting go by Sarah Edelman...
I also downloaded when sleep was evasive an app called white noise you can then play various noises that will help soothe you through sleep ..... I liked a combination of waves and thunder
Don't ever feel sorry about needing to vent and share where you are at right now on your Roller coaster ride you didn't chose to get on.
Gentle hugs and energy to deal with the day ahead ...
