If it is anything for you to know, I've always going through anxiety and low opinion of myself too, I just hide it as best as I can with a bit of drink to tackle it. Not healthy I know but it gets me through...funny you mention the old theme park documentaries, I was watching the documentary of the building of the Alton Towers Hotel and of that Andrew Hollingsworth presenting it...looking back on it, I miss the days when many British documentaries in the 90's used slightly awkward or drunk dads to promote the park rather than all those annoying internet personalities nowadays.
