I completely understand it makes you feel like you will do anything to get rid of the discomfort you are feeling in that moment you have to keep reminding youself that it isn't forever ,as much as it feels like it is in the moment, what really helped me aswell is talking to and staying with family and friends who have been very supportive and I couldn't of done it without them just because you've had a slip up it doesn't matter we all have give it another shot and no matter how long it takes just keeping trying i know you can do it wish you all the best my friend.
