Moving back to UK, advice needed please in regards to benefits

Have been living with my parents in Switzerland for the past few years.
They are basically my carers because I suffered a nervous breakdown a few years ago and since then
I have suffered from health anxiety and panic attacks.

I miss living in the UK so have decided to move back, but I have so many questions in regards to the move
as well as what benefits I am entitled to.

My parents can't afford to travel with me and help me get settled in England, so I will be making the move alone :(

Is there a caring service that can assign someone to help me with finding an apartment and therapist?

Ideally I would like to find a flat BEFORE I arrive in England so I can move in immediatly instead of staying in
a bed and breakfast while I search for an apartment, because that would be expensive if it ends up taking me a month to find
an apartment plus it would be VERY stressful.

Also, suggestions of nice areas to live are appreciated :)

THANKS SO MUCH EVERYONE FOR YOUR HELP! :)
