Chemo really takes a toll on our bodies and mind. Those drugs definitely effect your mood and this can effect how you cope too.
I felt so awful during my last 3 chemos and was just so over the dreadful taste and the aches and pains. I hated feeling down particularly because my family had been so wonderful but I was sick of missing out and not seeing people and felt that no one else understood how alone I was feeling.
It felt like I had worn everyone else out too! I could not exercise much because of aching muscles and breathing issues and I just felt in a slump that I could not get out of.
I did not get any counseling but have had counseling for other issues at other times in my life and found it beneficial to use the skills I had learnt previously.
I do feel back to normal most of the time now ( still have moments though) that chemo is out of the system (last chemo was 7 weeks ago).
It might be worth trying counseling but you will probably find that life will improve when chemo ends. I find that now I am back exercising I feel so much better in my mood. My positivity is back, along with a new determination to make the most of life.
Hope you feel better soon but you are certainly not alone in your feelings. We are enduring a traumatic time and we all feel angry that this has happened to us and that our lives are changed forever and that others just don't understand.
Take care. Deanne xxoo
