Resentful

I think I am turning into a weird bitch. I was going to the underground station a few days ago when there was some charitable sale of flowers, ₤ 4.50 a bunch, quite pretty, oh they are for CHARITY. At first I did not realise they were charitable, but then somehow for them to mention charity this became quite a sensitive issue. There was something within me that wanted me to say to the guy out loud, 'How dare you ask me to do charity? I have done so much charity that I am sick (not sick of it, but physically sick) and risked all my life and in the absence of ₤300,000 in my pocket I am in desperate need of a lawyer, do you know how much suffering there has been in the past 125 years and beyond and how much suffering will be reduced in the next 125 years if only I get a ₤300,000 -yet-free lawyer?'
Next time I really might kick off an awkard conversation saying- YOU SHOULD DO CHARITY TO ME!!!!!!!!!!!!! NOT THE OTHER WAY ROUND!!!!!!! I LOOK FINE BUT HAVE YOU ANY IDEA HOW MUCH I AM VICTIMISED!!!
Oh dear, with the resentment I am slightly mentally imbalanced.
