Welcome, @Needlephobia , I'm sorry to hear you're suffering from this. Well done for reaching out.
Do you have a psychologist or counsellor to help you through the stages of tackling this?
I'm not a doctor so this is not medical advice, but I have a few phobias and as I understand it, the answer is exposure therapy for mine. For instance, exposing yourself in small increments to your phobia. I find it incredibly difficult and it's definitely something I need professional help and support for. If you are throwing away the blood test forms, then you might need professional support for yours too.
It's a matter of tiny, tiny steps over time, so well done for wanting to tackle this now before your daughter arrives.
If you don't have a psychologist or counsellor, then the first step is to visit your GP and ask for a Mental Health Care Plan. This will entitle you to 10 subsidised sessions with a psychologist per year. The only thing is that psychologists are so overwhelmed with demand at the moment that it could take 6 months to get in to see one. But it's a good idea to get on the waiting list now.
You can help this process by googling then ringing round psychologists in your area to ask: are they taking new patients at the moment, what is the wait time for a new patient to start, what are the costs, etc. Then you can take a name to your GP for the Mental Health Care Plan referral. (GPs might not know which psychologists are taking new patients and which have stopped as they are full.)
Good luck...
