It varies from person to person. Some people feel it within days, some people need months. I started seeing small improvements within 3-4 weeks, but significant improvements only happened 6-7 months later. Full recovery took me about 2 years, but my case was severe. The worst mistake I made was setting up a deadline for my recovery, until I finally learned not to do it. It creates false expectations, increases anxiety and decreases benefits of your emotional and psychological work. Do not make the same mistake!
