The moment you realise you have nothing you want you kinda need to snap yourself out of it, reconnect with who you are and the kinds of things you enjoy and cultivate a personality again.
After my mum had kids she ditched all her friends, declined any invitations, refused to see any relatives and just sat at home gormlessly watching TV shows she couldn't follow and could barely remember well enough to talk about. She bought shapeless grey clothes to wear then took me shopping every Saturday to go around the shops saying "I'm too old to wear that" and "I'm too old to do nice things" (she was mid-30s.) She refused to go on days out, watch movies, read books, have any fun whatsoever.
The kids moved out. She simply went from 30 to almost 60 watching the same shows, having the same conversations, never seeing anyone. I try and take her to the theatre, cinema, shopping, days out, but she just says "I don't enjoy anything."
After I had kids I was terrified of becoming the same way. Imagine! Never enjoying things again. Never feeling fun or laughter. I tried out old hobbies, took up new ones, said yes to any invitation, I travelled alone, I studied. I always have things I want, goals in mind and something to ponder. It's just something I really prioritise. I refuse to forget who I am and spend the next 30 years comatose in front of Countdown and Cash in the Attic by myself.
Anyway. Point being.
Worry a smidge less about the wishlist for now and focus on you. What did you like before? What do you fancy trying now but never did? Google a bit, see what's on in your area and what you might like to go and do.
Work on that, on yourself and your personality and what you enjoy, and the rest will follow.
But please, it's so sad to see anyone say they "have never really had money" or they "don't want anything."
