I think I have just become completely paranoid about food that now the issue has become a social anxiety. Work lunches and dinners just make me anxious. To top it all off I've been invited to a wedding and the thought go having to eat somewhere like that is making me feel stressed out.

I am searching the net for a support group but I'm struggling to find one.

Is there an allergy support group or someone else you can talk to close to home, like a pastor, counsellor, or trusted friend?  Once your allergies are under control (you know what they are and can avoid them), you may also want to seek the help of a psychologist who specialises in anxiety, particularly anxiety due to medical conditions. 

I just feel like I'm totally alone and that I need to be fixed. I have spent so long looking into desentization and even so called cures.

yes, I think that such feelings are actually quite common.  I felt a sense of anger and betrayal, even, as peculiar as that sounds-- it was like there HAD to be a reason why it happened.  I wanted something to blame.

I also felt very, very alone.   

While that isn't so, it can sure FEEL that way when most of those in your daily life don't understand what you are experiencing, or that you aren't doing it because of poor mental health.

I really need some help am I the only one who is gong through this. I have spent years going back and forth between the GP trying to get these allergies under control. And now that I have this diagnosed I have gone into this mode of shock, anger and depression. Whoever I speak to about this thinks it's no big deal. But to me I feel abnormal and that there is something wrong with me.

I'm just venting anger and I'm paranoid and stressed. Has anyone been through this? Is this just me?
