Hi Ele, I personally don't think it is too much but I may be biased because I share similar beliefs. But the way I see it is that no matter what you write about you will always have persons who oppose your views and I don't think you should let that make you second guess your writings and the messages that you want to share. That is just my opinion.
I read your post and I didn't see anything wrong with mentioning your Faith in your Post. The most important thing is that it helped you come out of a bad situation. I have a category on my Blog for my Faith-based posts. I believe that my Blog is a ministry.I minister to both the physical needs and the spiritual. If a reader does not like my Faith posts, the person can skip it or choose not to read it. I aim to attract people who love me for who I am. That's being sincere and real.
I even realized when I did my analysis last week that my visitors increase on the days I do my faith based posts. My Blog is still new barely 3 months old but I believe in Keeping it real. I am always attracted to Blogs that the owner is not ashamed to speak about their faith and I believe there are people like me too who would want to read your posts. Keep being real and keep it up.
