I don't post on here much but saw this and thought if I could help even a tiny bit then it's worth saying something.
This is something I have suffered with myself and have pretty much overcome now. What you need to get your head around is that you are not scared of the situations you are in. So, you're not scared of being around people or at a football meeting. What you are fearing is the fear itself. Those feelings of panic and anxiety.... Now, if you then can get your head around the idea that these feelings although horrible (trust me, I know) are not going to kill you, you are not going mad and they WILL stop once the adrenaline stops pumping this will start to help. Once I realised I wasn't actually scared of the situations but just the feelings themselves I started to get better. I actually would then try to make myself panic, try to bring the feelings on to show myself that it wouldn't hurt me - guess what, I began to stop fearing the fear and the panic is starting to go away. I do have Beta blockers for very occasional use (say for example i'm doing a big presentation) as these stop the release of adrenaline so I know i'm going to remain calm but other than that i'm about there...
Happy to go into more detail in PM if you need. I'm no medical expert but just a little bit of my own experience really, I hope this helps in some way, I know how bad it can be.
