I know exactly what you mean about talking to others about their problems, and for me, the answers seem cut and dry, shame i can't apply the same logic to my own life
I posted a huge long post to you earlier and my computor crashed .
Let me just tell you what happened when i went to the doctor, of course a lot will depend on your doctor and the services your health centre can offer.
I basically broke down, completely, was hysterical in the clinic over something trivial (i thought my tonsils were tumours - i suffer from severe health anxiety). My doctor was lovely, not over sympathetic, i didn't want that. There was not one mention of social services nor any questions about how i cope with DD. Which i do, most of the time. Please don't worry about this, you recognise that you have a problem and you are doing something about it, that makes you a better mother than most. I was given the option of ADs which i didnt take at first, and my doctor was totally OK with that, you will not be forced onto ADs, but they will be offered if they think you will benefit. Taking ADs does not mean an admission that you are depressed (although that in itself is not a weakness or the end of the world). I was given them for anxiety, which really sounds from what you describe is what you are going through - i have found them really helpful for that side of things. I was given counselling which for me was as useful as a chocolate teapot, but if you can get CBT that will be a real help. You might have to be qutie assertive to get this.
Write everything down too, makes things easy to remember. If its hard to talk, just give her the note.
I think its good your DH wants to come along, he wants to understand too - makes it easier for him maybe to understand, but that is up to you.
You sound very strong actually, you will get through this. And please stop beating yourself up over this, you have ishoos, you say. That means you are unwell, its physical, you are not a wallower or weak - just need a pick me up. Yes of course there are people with more concrete problems around, most of my problems are in my head, it doesnt make them any less real. Some of those poeople will need help, others wont - we are all different. But you are not weak and you WILL get over this.
Do let us know how you get on
