Sounds like you came to a good place to get some much needed support. What is your current profession?
I know I needed a good plan when I decided I really wanted to quit for good, I also needed the support of family, friends and people on here. You can do it with the right focus.
Please don't get discouraged, we have all been where you are and there is a much better place you can be. It takes time so just realize it won't happen over night.
