Feeling terrible for you! We all know what it's like.. I had agoraphobia for about 5 yrs and missed SO much. It really is a horrible way to live. But Its going to get better. It really sux u had to miss out on your son's graduation, but Im sure he isnt mad. & if he is now, he wont be forever. This is the worst phobia to have :/ It will be okay tho, things get better!
