All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
May Allah reward you greatly for your adherence to your religion and we ask Him to enable you to do whatever He likes and whatever pleases Him. We ask Allah to make a way out to your difficulties. You must sincerely repent to Allah and not take a loan with Riba (usury and interest) again. Indeed, Riba is one of the grave major sins. You should fear Allah in your future life and He may forgive you for what you have committed in your past, and relieve you from all difficulties and provide for you from sources you never could imagine. Allah Says (what means): {And whosoever fears Allah and keeps his duty to Him, He will make a way for him to get out from every difficulty, and He will provide him from sources he never could imagine.} [Quran 65:2-3]
If you can get rid of this interest, you must do so; otherwise you should pay back the whole loan and ask Allah to help you.
Allah knows best.
