Hello Saoirse,
I agree with all of the smart people responding to you. That first month is all about bearing down and getting through 1 day at a time. Getting in a routine, at least for me, is crucial. Check in on the daily threads here and commit to 24 hours. Check in as frequently as you need to. Start making healthy choices in your daily life because they tend to turn into other healthy choices. Above all else, don't lose hope, don't take the easy way out.
