Pris , Talk with your Oncologist nurse or navigator and let her know that your are having these feelings. I know it's hard talking to family and friends but the nurse, I'm sure, has heard this before and can help you with either changing your meds or letting you know if there is something that would help you.
These are very common feelings and you are by no means by yourself with them. Our emotions gets pretty high and with all we have to go through it's a wonder we aren't worse than we are. Hugs and please call the nurse.
