I don't know about the ivig but wanted to welcome you. This is a wonderful forum. I'm new to this and am younger not as you but 28. I understand the friend issue and feeling alone. Try not to give up hope and make sure to use your voice. A few things I have learned about docs and apts. Have ?'s ready to ask and don't feel rushed,bring all results from past docs and tests to the next,get another opinion. As for your friends could you try to educate them and how they can help you? I think often people don't know what to say or how to help. No one can understand completly and I especially think young people who have been through little have an especially hard time. Just know your not alone and if you want an email buddy I'm here always. Take care and though so hard as I fear always too but try to stay in the moment.
