This is my first post in this section (have namechanged) i don't feel confident enough to talk to anyone in real life about this but it's starting to take over my life.
My back story is that I suffered from severe anxiety a year or so after my first baby was born 15 years ago. This mostly centred around food/vomiting. It didn't happen slowly as far as I remember but I may just not have noticed it creeping up I suppose. I just woke up one day and couldn't even sit up without feeling horribly sick.
I won't bore you with the ins and outs but what followed was around a year of near constant panic attacks, I was unable to leave the house at all in case I was sick or in case someone else vomited in front of me
, I wouldn't allow anybody in to my house for the same reason, I barely ate anything just dry bread, the smell and sight of food made me sick and I lost a huge amount of weight.
I had cbt over the phone, and slowly things got easier and I got better. I've never been anxiety free but have found I've been able to talk myself down and rationalise what I'm feeling until recently.
For some reason I've started to have unhelpful thoughts about having an allergic reaction. I don't even have allergies, I never have except for hayfever/asthma. I don't know why this is happening to me now 
It started with being anxious about taking medication, I've always been wary about it, but it increased until I now can't take anything except for paracetamol in case I have a reaction.
It then progressed to sillier things like dying my hair, body lotions, different toothpaste etc, and then the food fear started to creep in.
The range of food I can eat now without thinking I can feel my throat closing up and my lips swelling is getting smaller and smaller and I don't know how to stop it. I just can't get like that again, I have more children now, 3 have ASD. I haven't got time for this I need to be on my game all the time but it's just getting worse every day.
Sorry for rambling on, I'm just really hoping someone here can give me some advice on how to manage this
