I can't get married because of my sickness. It's lonely but I am coping. A good way to keep your enthusiasm up is to write letters to Allah talking about your future wife or wives or however it works in Jannah firdous inshallah. I think the best compliment one can give ones future spouse is praising her beauty to Allah before you have evens met her mashallah. So write something to Allah about your future wife and when you are married show her the letters inshallah. It really helps me, I hope it helps you too inshallah.
