I would tell her. My mom is a great source of comfort and support for me. She may take a while to understand what you are going through but eventually she will catch on. Just talk, and keep talking until she feels she can understand and help you because that is what she will want to do.

Tell her when you're ready. I struggled with this also for a long time. I ended up telling my parents by accident but it was the best thing that has happened in regards to my depression.
I do wish I had have sat down with them and told them properly.

She won't be disappointed I'm sure. It's not like you've done anything to deserve this. If she was disappointed it would be because she doesn't understand. So maybe when you tell her print out some information on depression for her to read.

Good luck!

tell her. it will be hard but shes ur mum. as a mum myself i know id rather know the truth about my daughter cos if i found out years later she had been carrying such a heavy weight for so long id feel guilty for not spotting it and helping her.
mums worry and fret yes but takes more than depression to disappoint us...... well certainly would for me. only disappointment id feel is that they didnt tell me sooner

As you know, depression is a normal 'thing' .. it is MAJOR or CLINICAL depression that is the disease. I think you should tell your Mother but how you tell her is important. I would not tell her as if it was a complaint but a fact. Something like:

"Mom, I am dealing with a problem. I have done some research and I believe I have major depression. It is complicated with a possible eating disorder (food addiction). I think it could be serious and I need to get evaluated, diagnosed, and on a treatment plan."

Or something like that. Often parents jump to the conclusion their dear child is 'just depressed' (normally) and will or should 'snap out of it'. That is what you want to avoide if possible.

My suggestion would be to tell her. You know your mom best and obviously you trust her. let her in. Love and support is just what you need in life. Letting her in will also make you feel better. It is so hard to live our lives without letting someone in.

So hopefully you will tell her then honey as i also think she would be better knowing......she will understand im sure and no way would any decent mother ever be disappointed by their children whatever they do. I always tell my daughter that whatever she does etc i will still love her unconditionally and i have told her she can tell me anything and she does....hope it all works out for you and again im sure your mum will be a big comfort to you as dp69 saysxxx

My mom is in her 80s now. I see no point in telling her.

Go with your gut.

I think telling her would be a great thing and could help you as another source of support and love that you need. Its important that you let her know, but also that you make sure she knows this isn't something she can "fix", that you have to do the things and take the necessary steps for yourself, but that she can be there to support you. This isn't something you choose to have, so she needs to know that you just take it for what it is and that you appreciate her being there for you. I hope the best for you my friend :)
