When I am with _them_ I have no anxieties.

I am not harassed at home by doubts of who people are, and confusion about names, and so on.

I suspect the contrast weighs a little on my mind and upsets it.

They make me over-suspicious among them here, and it ends in my feeling doubts and fears that I can't get over: doubts about you and fears about myself.

I have got a fear about myself now.
