How Is My Life About To Change?

So I was just diagnosed with Epilepsy two days ago after having a couple seizures a few weeks ago (followed by an MRI, EKG, and EEG; the last of which left no doubt). They were Grand Mal/Tonic-Clonic/Whatever that left my memories and intellect in an unassembled puzzle. I am a 41 year old man that travels around the world and teaches software in the Commodities Industry (a.k.a., speaks in public for a living). After the diagnosis, I realized that I have probably had seizures in the past while I slept or something and simply didn't realize it. The best I can describe it is that I simply woke up feeling a little dumber and more confused for a week or so. I stayed quiet and hid it as best I could until I felt normal again... They have me on 750mg of generic Keppra twice per day and I am about to return to work after a couple weeks off. Here is the real kicker.... I am not writing this for sympathy, snarky responses, or generic quotations from WebMD.... I am either going to be extremely grateful or disappointed based upon how honest even one of you is willing to be with me regarding one simple question... How is my life about to change? I'm a grown man, and I am scared. There you go.... Speaking in public for 8 hours a day for 5-10 straight days all around the world is taxing and completely fulfilling. The thing is, unlike most jobs, I can rarely say, "Let me get back to you tomorrow" when I am having trouble putting facts together that I should know. I need to know right then. I feel like I am back to about 90%, but I feel like I have plateaued. I am not someone that teaches or speaks in public because I am full of myself or need attention. I simply love helping others achieve. I am not scared of making a fool of myself. I am scared of letting my students down. The generic Keppra makes me pretty tired, but that is about all so far. If you are reading this, then you have either been through it and are doing great and might have great advice, been through it and are still struggling and have valuable warnings, or are in the same boat as me. Can someone tell me what I am in for during the next few months, then year, then the rest of my life? I have always been the smart and entertaining guy that loves teaching and empowering others. Will I ever feel the same? Life has definitely thrown me some curve balls and unceremoniously kicked me while I was down several times over the years, but it has never humbled me like this. Holy cow, a seizure that scrambles your memories is so humbling that I would actually call it embarrassing if I wasn't so afraid of upsetting others. It's a feeling I have never had. At the end of the day, here is the single thought of a man that has just been told he has epilepsy.... I can't say I am having a meltdown over it, or handling it with no problems at all. I guess what I am feeling is simply that I am having trouble wrapping my head around the news and what it actually means in my day-to-day life. I do not understand how my life is going to change. I have to figure out what I think and know before I am able to discover and admit how I feel, yet I apparently am still very capable of feeling complete fear... I go back to work on Monday, and I will be in front of an auditorium of people within a few weeks. Will I still be me, or will my intellect, wit, and focus be compromised? Please... I don't want sunshine or smoke. Will someone just be real with me? Truth will either remove fear or make you aware of what you should actually fear. THAT is what I am asking you for. That is what I need right now. I am sorry for being so long winded. I am just hoping this touches just one of you enough to actually respond and reach out to me with some honesty. Thank you, Mark, in Houston
