Small Writing? Could you explain my mistakes? Thanks for your help

How are things going on? Whhat's the weather like? I hope you're doing fine and enjoying the warm weather. Things are not bad for me. Howebver, nothing interesting is happening in my life now.
It is unseasonably unusually warm here and the temperatures' are above zero.
I came home with a splitting headache. I got so tired at work that my head was throbbing thunbing. I 've taken some painkillers and I hope my paimn pain will go away soon.
Yesterday I finished reading a small story about Stalin camps by Solchenitsin.
Since on Monday and Tuesday we are going on a holiday I will have a long along weekend.
I must say you goodbye since I need to do household chores.
