My son's life story... and Im so confused!

My son has been having seizures since he was 12 months. He has also been a breath holder since birth. Around 9 months he started holding his breath to the point of passing out, then at 12 months he came to after passing out, but he wasn't there. His eyes were blank and his arms and legs were rigid. I thought he was dead... I had never been so scared in my life. After taking him to emergency via ambulance i saw three doctors, to which all of them said he did not have a seizure as seizures cannot be provoked. Thus starting my long journey to find out what was wrong with my son. 2 months later he had a nother passing out episode to which this time his whole body shook (It looked like he was doing sit ups) and he took much longer to come to. He had had a low grade fever, so after a million tests (ECG etc.) he was sent home saying that he was fine. Once again I was not satisfied so off to a ped who looked into and EEG. The results came back he was fine, so I was then accused of being an awful mother who took her child off formula to early and that basically he was anemic and to just give him iron and he would be fine. My son is now 22 months. He holds his breath up to 4 times a week, sometimes all in the same day, and passes out, and 3 out of 4 times his eyes roll back he stays stiff and then comes to, and is so tired and clingy. The other day he slept for 4 hours after having one. Since the last EEG I was referred to another ped in which they did another EEG at a hospital for children. The EEG was completed in July, I have been playing phone tag with the doctor since then. Just on Friday she calls me to tell me my son has epileptic abnormalities on the left and centre of the brain. I was shocked. She said that only because he had the one major seizure back in December to not give medication and to just keep an eye on it, as the side effects are worse. So now I am so confused. Does this mean he has epilepsy? Do they just grow out of it? What about the breath holding? Should I be doing more tests? Like an MRI? I really don't know. If anyone could help me and my son...
