Support forums like PC are good. Blogging is good too. If you have the courage, you can create youtube videos.
An even better idea is to create your own support system in your community. There are many websites where you can create your own online support community. Some are free to create, some cost little money.
If you want to take it a step further, you can create a face-to-face social group that meets every week. There are many sites you can do this on.
It you want to build your own group in your own community, it will take time and effort. One of my friends created her own social group for sexually abused victims in her closed-minded community. She went from 1 member to 27 loving supportive members. It took her 4 years. You can accomplish anything, as long as you believe you can.
