unfortunately both of the things are tied, especially when you feel a loss of control in your surrounds/life.
^ to the both of you you can beat them both!
i'm in the same situation (have been for many yrs) and i'm well into my recovery for both so it is possible :)
not saying it's easy but it is so worth it !
this (
click here for link ,applies to all bold text on this relpy) is a topic i wrote awhile about SH and techniques i found to help stop/reduce selfharm but use the site's search bar and type in key words as there are some good self help topics here as well as on google/ the web.
butter fly project
some useful
techniques in the comments and video my help
as for ED's (using as a umbrella term to cover them all) these are some basic principles that may work for you, personally i found some of them did others didn't as much..
set alarms to remind yourself to eat and stick to them. even if it's something like a piece of fruit or something, take time out from what you were doing and take some energy on board, not easy at ist but i helps create a routine and you can gradually increase intake or whatever you need to do to improve your disorder.
As for binges.
Through all foods your likely to binge on out and dont buy them in the next food shop, yes binges will happen now and then but comeing out of them positively rather than beating yourself up over a slip up in progress , makes them more bearable. also learn when you feel like you're about to binge and avoid places where you'd usally go, ie bathrooms, kitchen etc and do something productive that require you too use your hands and mind.
ie draw, dance to upbeat music, game , go for a run etc anything to get yourself and your mind away from the area.
as you both know after a while you can distract your mind away from things if you do them long enough.
heres some links and sites i've been using/found during my recovery:
Bulimia help
The help guide.org
Beat (a site i now work closely with and found very helpful!)
online self help community
information links
Mind.org (great site for any issues related to mental health inc SH and Anxiety)
Student minds- ED recovery
the support line.org (loads of useful links and info all in one place)
Seed (a ED self help site,lots of info and techniques )
