Making dua for aafiyat and ease

Q: I have been experiencing alot of difficulties in life over the years and just can't be happy despite trying many things to remove the difficulties. I am always sad and depressed.

Many years ago around the time my problems started, I read a book about some of the pious people of the past. In it there was a narration about a well known pious person being seen in a dream by someone after he passed away. The person asked this pious person about his condition in the hereafter. The pious person said that Allah granted him a place in Jannat near the Sidratul Muntaha because he was always in the state of huzn. Immediately I made dua "Oh Allah, keep me also in the state of huzn and grant me also a place in Jannat near Sidratul Muntaha" without even knowing what huzn means. Some time after this I remembered this dua and found out what it means.

1. Could it be because of this dua I made out of ignorance that I am always depressed and having problems in my life?

2. If it is because of this dua, what do I do now to put an end to my problems and constant state of huzn?

Becoming a ma'zoor due to constant discharge

Q: I have read on many trusted sites that, urethral discharge is impure. However, if someone is getting this discharge a lot and it is difficult to control, can they be excused from washing it constantly? I experience a lot of anxiety and stress and is probably why I am getting this type of discharge. I know from experience. I don't want to be stuck in the toilet for a long time or use a lot of water.

1. So what can I do? I've read somewhere else that a girl used to experience this discharge because of severe headaches, so she was advised that its not the normal urethral discharge.

2. Doesn't it make you najis because its coming out of the place where urine comes out?

Taking hair loss medication that causes impotence

Q: I have a question regarding a medicine by the name of propecia (finasteride). It is a basically a hair loss medicine. I will put it this way:

1. This is the only proven oral medicine to stop hair loss and regrow some hair

2. It can have some side effects like loss of sex drive and impotency.

Being unmarried, loss of sex drive helps me to stay away from haraam as well as preventing further hair loss but on the other hand there is a chance of deliberate impotency which could be permanent. Please guide me which path should I take.

On the one hand I want to preserve my hair but on the other side I might not be able to marry if it causes sterility.
