Hey there!
I know you've probley heard this before but having an eating disorder is not just about making yourself sick or starving, its about how you think and feel about yourself and life which is usually in a negative way. People who suffer from eating disorders don't just have low self esteem, they usually have no sense of self at all.
An eating disorder is a way to cope with life but is a very destructive way and can cause alot of medical problems as well as alot of pain mentally.
It can be very lonely and very issolating at times.
I would really reccomend that you get help because this can really take over your life.
I really hope that you tell your mam because she can help you. I can't tell you how much this can control your life and even ruin it. I'm talking form personal experience.
It isn't a way to live, you begin to just exist rather then live.
I have lost all of my friends and so much more, you deserve so much more then that.
You desevre to be happy and content with yourself and your life.
With regards to your dad, itsnot your problem that he wants you to lose weight although I know it can be tough. What reasons he feels that you need to lose weight I think he should ask himself why that is.
If people are truely happy with themselves then weight doesn't even come into their minds, its not about weight, there is always an underlinding issue and with regards to eating disorders there can be many different things which have caused it.
Your father is not right in telling you that you have to lose weight but thats his own stuff, when you said that I just thought well what is it in him that he values weight and appearance so much, he could have certain issues that neither you or him are even aware of. I know this is a difficult thing to ask of you but please do not take it personally, him wanting you to lose weight has nothing to do with you but him.
You are good enough, always remember that! He cannot make you feel not good enough if you don't let him.
You are the one who can chose to take what he says on board or you could chose to realise that he is the one who needs to deal with certain things and you should chose to consentrate on how good enough you are and how great a person you are.
I know I might not of helped but if you need to talk or have an questions please write to me anytime.
I hope your well,
take care!
