Hi all, 3 years ago I was diagnosed with cancer of the tongue. I was in the prime of my life, fitness, happiness and had a great relationship.

I got through the cancer successfully, lots of operations and radiotherapy. My partner was supportive through everything. Depression took hold after this as my life was turned upside down.

I have taken antidepressants had counselling and neither have worked. My partner and I have been having problems with our relationship for about 18 months now. I am not the same person she fell in love with.

I find it difficult to enjoy life now, and I am quite content with a simple routine. This is mainly because I am always fatigued.

Recently my partner cheated on me as I wasn't giving her the attention she wanted. I found that very selfish after everything I have been through. I want to forgive her but I am unsure if I can.

I want her to be happy but I feel like she doesn't understand how my thought process and lifestyle has changed.

She is always angry with me and blames me for her unfaithful act which I find extremely unfair.
