Hi, Riversong. I just replied to your post in the new members forum, suggesting you get professional help, such as a pastor. I also mentioned that the Bible is a source of guidance and comfort.
As far as believing in prayer, the Lord hears every word we say and every thought we think. He loves us all. Paul instructs us to pray constantly (1 Thess 5:17 RSV).
The Lord does not like sin, though, and you say you have some addictions. I suspect he wants you to fight those addictions. It seems likely to me those addictions are what is pulling you down.
You say the addictions are too hard to fight. Well, addictions are not easy to fight. That is one reason the Lord told us to stay away from the things that we become addicted to. The Lord will help you, though. When you defeat your addictions, I think you’ll find life to be beautiful.
