Are you firmly attached to your handbag?

Sounds like your handbag is your security blanket Flyinghandbag nothing wrong with taking it with you if that makes you comfortable.
I'm sorry you feel so nervous about everything, have you talked to anyone about this.

During the lock-down I haven't needed my handbag but I had to find my Green Flag card today to arrange to have the car's battery recharged. Naturally, it was in my handbag.

Got mine at the charity shop never know where it is it serves a purpose though because my pockets aren’t big enough for keys, phone, tissues and purse
How do you use a wardrobe drawer against a burglar ?
No idea who Davy Jones is apart from his locker or was he in the Monkees

I have a couple of smart handbags for going out, to funerals etc. For everyday I favour a backpack. I have two they are small, but still hold everything I need even my water bottle and a picnic.

Half the time I don’t know where mine is !
