Hey, totally understand how you're feeling, but I think you've just got to prepare yourself for the new life and the joy you will feel having hair. Amazing how folks with hair will just take for granted that they have it, whilst us receders have all this hard work of concealers etc just to feel we look ok.
I'm about to start wearing, ordered and waiting, like you, a bit nervous but mostly excited. I was getting fed up of having to take 30mins to 'do' my hair and direct it into a pattern that doesn't look too much like a comb-over, or horrible side-sweep etc, then you've got wind and such things. It got to a stage where I decided to stay in because it was too windy, and I knew I couldn't ware a hat if we went outside because I'd have to take it off to get into a few places, then I thought, it's time for a system.
I've been growing my hair a bit recently, and wearing a lot of caps quite often. I've also been made unemployed recently, but had an interivew yesterday, so my friends have seen me with longish hair or with the cap, and the concealers etc. I'm hoping once the systems arrive, it'll help blend it in, get a short hair cut, been working out/losing weight, and growing some stubble round the face.
I don't honestly think people examine hair as much as we do on here. We are subconcious about it, but I think folk who have a lot of it are not. I remember once I had a hair accident and tried to cut my own hair but ended up shaving it too far in. So, I had to just shave it off, and it showed off my V-shaped recession - People would comment on it, Even was called 'Andre Aggasi' at one point
but as soon as the hair grew back, I remember we were talkign about baldness one night in a bar with my friends, and they all agreed that all of us had good hair for ages, (mines heavily disguised through combing it down) forgetting that 4months previous I had a V on my head.
