Making taubah for taking an interest loan

Q: If a person, who in ignorance, took out an interest loan, thereafter realized his sin, made sincere taubah and made a promise to Allah never to take such loans again. However he still has the debt/loan to pay off and he doesn't have the full amount to settle it. Now going forward, does he still fall under the curse of Nabi (salallahu alayhi wa sallam), as he still has to pay off the loan and he will still be paying interest? Please advise whats the way to correct the situation.

Suicide in Islam

Q: What does Islam say about a person committing suicide because of black magic? I know suicide is haraam in Islam, but if the person who committed suicide was a really pious man, prayed five times a day and lived his whole life according to Islam, but in the last month of his life, he started seeing things who were telling him to take his life, not to pray and eventually he took his life, then what is his status?
