hardship

Scholars of Islam, As-Salaam `Alaykum wa Rahamtullah wa Barakatuh. I have faced so many difficulties in my life that it has made me hate this life. Every time I turn to Allah, I implore Him to take my life at the earliest. This is my wish until now as I do not see any solutions to my problems except death; it is the only thing that can save me from this unbearable life. Is this behavior forbidden?

Dear scholars, As-Salamu `alaykum. I want know which is better in reward: to travel for Hajj by plane, car, et cetera, or on foot? Some people went from Pakistan for Hajj on foot claiming that they will get a greater reward. Is this true? Jazakum Allah khayran.
