I am absolutely disgusted at lots of these comments on here. There's so much talk about the stigma around mental health and how there needs to be more understanding....and a woman comes on here and shares how she can't manage to control her condition and all she is told is what a terrible partner she is, how her DH is going to leave her and how she needs to pull herself together. You know what? Her self-esteem is low enough as it is. Not helpful, any of that. And also pretty bloody presumptuous too.
Don't bother @ me with replies telling me how wrong I am. I'm too pissed off with what I've read to talk to people who are judgemental and clearly don't have a fucking clue how debilitating severe anxiety is. The OP has suffered this since a teen. You don't reverse that simply by trotting along and meeting an enormous challenge the therapist sets you. You need intensive support to keep going and keep trying and sadly, the NHS is just not able to provide that. The services they deliver aren't sufficient because they're so desperately short of resources. Mental health services are basic, at best. OP has TRIED FFS. She went to therapy, had CBT, tried meds. She needs intensive help and support. It's not just about pulling yourself together.
Having said all of that OP, yes you absolutely need to try and get over this, but you need help. It's a big battle for you as it's so entrenched. And yes, while your DP may be very supportive he's also an enabler - he's probably so exhausted he's just taking the easiest route possible. I get why he is, but at the same time that's not going to help you take the steps you need to get better.
I absolutely second selective mutism. Maybe autism. Look into it and see what you think. I have a daughter with selective mutism and a son who's quite profoundly autistic. Neither of them could just "pull themselves" together despite what some vipers on here seem to believe.
What I think might help:
Meds
Hypnotherapy combined with CBT
Possibly EMDR
Potentially speech therapy
You might not get all of those on the NHS - are you in a position to pay privately? I'd especially recommend the hypnotherapy. It's not a magic wand but can help equip you with the right skills to feel able to tackle what you need to do.
The therapist was right, you do need exposure but when you're at such a low ebb it can feel impossible to ever be able to give it a go. To climb the mountain, you need to put your boots on first and I think hypnotherapy might be just the support you need. I'm not a hypnotherapist by the way haha! But I've had hypnotherapy for a different type of anxiety and it worked for me. Plus meds. You say you don't want to be dependent but you're already dependent on your DH....plus many meds aren't addictive these days anyway.
Sending you huge hugs. You know you have to tackle this and it won't be easy. Talk to your GP, see what they think about private treatment options too. When you're feeling more positive you might want to consider couples therapy with your DH too - only you can tell if that would help.
Just don't give up. I used to think of my children and how I wanted to do it for them, and it helped push me when times were hard. All the best x
