Strengthening one's Imaan

Q: I was a non-Muslim girl with staying with parents. I left my home and parents without any reason. I left my home when my age was 17 and now I am 29 years old. I converted to Islam at the age of 18 and still am. I had stayed alone and still stay alone. I have went through many hurdles in my life and still going on. Many people used me for their benefits. Now a days I don't know why but my Imaan is getting weaker. It is not like that I don't trust Allah Ta'ala or have no more faith but due to my problems and not becoming any good things in life I am getting worried.

There is much more to say but don't know how should I open up as there is no one in my life to share my each good and bad things.

Urine drops

Selling perfumes with synthetic oils

Q: I'm doing business of non alcoholic perfumes and Attars. The fragrances, which I sell come from a company in india (total hindus), keva fragrances. This company also uses synthetic animal derivatives such as civet oil, etc. in their perfume oils. They said, we can give halal declaration of any product, but did not show any halal certification. 

Secondly, this company is partly owned by blackstone, a giant company of USA, which deals in real estate, credit, equity, etc. involving interest as well. My question is that whether it is preferable to sell their products to earn, as they are strict Hindus and might be involved directly or indirectly in interest also. Secondly, the use of synthetic animal derivatives in fragrances are halal to use and sell?
