Friends needed, looking to loose 200 lbs

I am 400 lbs and need to half my weight, there is no way I can do this alone, I have the doctors behind me for health checks, I have the PT starting to work with me next week but without motivational friends and encouragement there is no way I can do this, I am looking for others in similar situation or others that have lost a huge amount who are willing to help motivate and encourage me on this monster journey
