Looking for wee adventures to cheer me up

Been a bit down recently. In my early 30s and I'm unhappy with how boring and unadventurous and lonely I am. Feel like I'm pissing my life away, just working then sitting home alone.

I've got a day in the city soon because of a medical appointment, what are some fun things I could do or see to beat the blues? I never really do stuff like this for myself so I'm not brimming with ideas.

Was thinking of maybe going to a nice bakery I saw in the West End, any other nice wee things I could do for myself?

Cheers ❤️
