Mocking Islamic teachings

Q: A boys birthday was on December 26 and I said to him that it was better if it was on new year.

Now my question is that I supported new year and I supported something haram (by saying that it was better if it was on new years day). I rejected Allah's rule and supported something haram.

1. Does it affect me as a Muslim? If yes what to do?

A boy said to me that celebrating birthdays is haram and I said that celebrating new year is also haram. Then I said that haram cancelled a haram as we do in maths where a numerator and denominator cancel eachother. Then I laughed and the the boy laughed too.

My question is that I made fun of Islamic rules by cancelling the haram of it in a funny way. I read in a place that making fun of Islam leads to a person becoming a kafir. Is it right? and does it have any affect on mmy imaan?

Bleeding gums

Q: I very recently had my wisdom teeth removed, and will have another one removed in the next few weeks. After my tooth was surgically removed, it bled continuously for hours (after such procedures, there is continuous bleeding expect for 24-48 hours). Now, I know it is not permissible to swallow blood, however I cannot continuously rinse my mouth, in fact rinsing and spitting to harshly after such surgery can lead to dry sockets which are very painful. I also find it very difficult not to swallow for such a long time (it seems practically impossible for me). What should I do about the blood in this situation? (Note that this is not a small amount of blood). Also, so far I have been praying by having a good supply of tissue in my hand or on the ground next to me and spitting the blood out onto those as I pray. Is this acceptable? Lastly, how do I eat in this situation (when whatever I eat will no doubt mix with the blood in my mouth)? Thank you so much for your help. May Allah bless you.

Running away without settling one's debts

Q: I am living in a GCC country for the past 20 years. I didnt have enough understanding with ribaa and was having bank loans and credit cards. In early 2008 I performed hajj and made alot of tobah with ribaa and after that I had chances but didnt take it anymore. Later my business got collapsed I got bankrupt and I couldnt repay bank loans. Since that time i owe banks money And my full intention was to repay the money somehow but I got total loss and now I am just jobless for around 2 years now in dire constraints completely. I want to ask you that if I leave the country without paying back the loans what I have trying hardest for the last 7/8 years...and there is no way to return and I am getting worse situation. Will I be held responsible or is it gonna be sin if I leave without paying as per my financial situation.
