Twice. Once on my own when my roomate left me high and dry to go live with her boyfriend and once with my husband. No regrets and had credit again within two years. Honestly it's probably the best decision we ever made. PM me if you like.
Have you tried any other options? The bankruptcy laws have changed in the past few years...they have made it much more difficult. Have you taken your means test yet to see if you qualify? I can offer you another option if your interested! Message me here for more info!
