There are many methods someone could use to CTB. The best one is the one that works for you. Some people use guns, some people drown themselves, some hang themselves, some use drugs to OD, some use poisons, others use various gases to suffocate themselves, some jump from buildings. Heck, some may even electrocute themselves. Pretty much every method imaginable is discussed in this forum. Sometimes it comes down to what you have access to. I know the OP doesn't have access to the search function, yet, but the OP should just start reading threads and learning if CTB is something they really wish to pursue. CTB isn't easy. Most successful
CTB's take learning and planning in order to achieve the desired outcome. Honestly, CTB shouldn't be rushed either, because you might make mistakes and the repercussions for those mistakes could be disastrous. CTB is a BIG decision, probably the biggest decision you will ever make for yourself, and you owe it to yourself to learn about different methods, their pros and cons, and make the best decision you can for yourself, and to learn all you can about your chosen method so you stand the best chance at success. And don't be shy about asking questions.
To the OP: You need to make a certain amount of postings as well as have an active presence on the forums for a certain amount of time in order for the "search" function to open up to you. That will make your searches a whole lot easier for specific topics you might be interested in. You should read and post in other people's threads in order to get your post count up, or start your own threads on pertinent topics you might wish to discuss.
Good luck in finding the answers you seek.
