I hope you will get better soon and that you'll always be healthy. It is normal that after such a serious operation you feel tired and exhausted. It is great that you are at home with your family after having stayed such long time in the hospital.

Two days ago was my daughter's birthday. We celebrated it modestly- only two cakes- but I bought her many nice clothes and a golden chain and bought small cakes and small bottles of juice for the children in order to give them at a small party in the kindergarden.

She was very happy that it was her Birthday. As for me, I am so indifferent to this holiday- every Birthday you get older and it is not a fun thought!

Today I went to the Immigration office to deal with my mum's immigration process. Again, huge queues and you have to wait in a small coridor without any windows. It was so hot there that you wouldn't believe that only two months ago everything was covered with snow and it was frosty.
Once again, my journey there was unsuccessful and there were so many people that I queued to no avail.

Your English is fantastic! I made a few small adjustments but overall that was incredibly well-written. I would love to be able to write like you in a second language! The only part I am confused with is the section in bold. Do you mean that you gave up on waiting because the queue was so long?

 

I"m learning English so I don't know if it's correct. But this is my suggestion

I hope you will get over soon and always be healthy. It is normal that after such a serious operation, you'll feel tired and exhausted. It is great you are at home with your family after a such long time having stayed staying in a hospital
