Charlie. Believe me, we all know how you're feeling at the moment. I was as fit as a fiddle before I was diagnosed in May 2011, so nothing could have surprised me more when I was told I had MM. I'd never even heard of it. When I started CTD I was still getting over the initial shock and all my thoughts were very muddled and illogical. I didn't even want to leave the house for a long time. It had a dramatic effect on me emotionally too. Good research done mostly on this site plus help from my specialist and community nurse helped me understand that a MM diagnosis is not the end of the world. I was told from the start that at the moment it's not curable but it is VERY treatable.
CTD was pretty grim at the time but I can assure you that all the side effects you get are TEMPORARY. When the drugs have done their job you'll feel your old self again.
Take everything one step at a time. Concentrate on getting through CTD before you start thinking too much about the next stage.
I had a weeks holiday in Wales during cycle 4 and everything was fine. I just took my pills with me and enjoyed myself.
I had my STC nearly 6 months ago and I'm feeling great, making plans for years ahead rather than limping from one 3 monthly appointment to another!
Take it from me, your life will get back on track. Try to stay positive and keep asking as many questions as you like. We're all here to help in any way we can. XX
