First off welcome to the forum Red

. You sound just like how I felt. I have been balding for the past few years and at first I could just style my hair to hide it. Eventually it got worse and I even resorted to using a concealer. Finally while I could cover it up with the concealer even that became more difficult.
Over the course of all that time, I used to constantly stress over my hair loss. I hated the wind and rain and would always wear a hat when those weather conditions were around. This past summer I even stayed out of the pool while my wife and kids were in it enjoying themselves. I often had an excuse like I am tired or have a headache which was true but that was not the main reason why I stayed out. Now when I look back it seems really sad and stupid that I did that. But that was the state of mind I was in.
I eventually came to realize that I had to do something and found this forum. I lurked for quite a while and then when I gave it more serious thought, I signed up to the forum like you did.
Honestly if you have cold feet about shaving bald right away(I did too), just go with a real short buzz cut like I did. I started with a #2 but immediately shaved it to a #1 because I thought it looked better and made the rest of my hair blend in better with my thinning spot. Once you go down to at least a #1 you will have a real good idea of what you will look like bald and it will allow you to get used to the look. Then when you are more comfortable you will either keep buzzing shorter(I went to a #.5 before I shaved it all off) or just take the plunge and shave it all off.
Like everyone else here told me once I shaved my head completely bald, I really do wish I had done it much sooner. Being sly is great and I feel so much more confident and love the look. I know that you will too once you get to that point. If you can not go sly right away, at least buzz your hair to get the ball rolling. That in itself will give you a nice boost of confidence because it will help minimize the appearance of your thinning hair. Take care Red and keep us posted. I know you can do it.
