Hi @Pennyblossom,
Welcome to the forum sweet. Complain away. We all have and do regularly.
Rollercoaster is about the only word that describes the emotional fluctuation of this shit fight.
Some people get a great deal of fatigue during radiation as well. Sometimes it's that you are nearing the end of active treatment and the whole thing has been such a draining experience and emotional upheaval it is going to take it's toll at some stage.
Teary is par for the course along the way and it can creep up without warning. Nobody can stay positive 100% of the time.
Rest assured what you are feeling is completely and utterly normal. You have to just let it wash over you until the tears become less frequent.
Congratulations on being at the end of rads, the goal post is in sight. Keep chatting, everyone here understands what you are feeling.
