Until better days come

My book talks about a totally mentally healthy woman who gets prescribed psychiatric drugs after her caesarian delivery (for pain), and after her original problems stop, she withdraws from the medication and is forced to go through a hell of discontinuation syndrome similar to if you stop taking heroin. And, in the book, it is really described in detail what she had to go through. During this huge withdrawal syndrome, she finds a support group where she gets to know a man who had stopped taking benzodiazepines in the past, who is almost healed now and helps now other people who came to the same situation to survive and understand what's happening.
In the past, during his withdrawal, he lost everything: his wife, children, his way of life. They start writing, he helps the woman very much, and they fall in love with each other. And they both realize that without the experience of withdrawal, they would never become the personalities they are now and that precisely this crushing experience enabled them to find their personal luck. They both become much better, deeper personalities.
They move together and start to live in Rocky Mountains in nature, without society and enjoy what they find the most important thing on the world - their mutual love, the nature, the hills, the meadows and their togetherness...
