I think you are being hard on yourself. You've had a lot to take in and I know chemo really impacted on my normal happy disposition. I am a crier when I'm stressed. Just have tears rolling down when I think of my kids or a memory. I'm always soneone who is a little like that but when stressed I can't contain it. Cry if you need, rest and regroup. Allowing the emotions to wash over, acknowledge that is how you feel and in most cases you will just find each day gets easier again. If it doesn't then make sure you speak with someone. Your breast care nurse would be a good start. Kath x
