My DD11 has been having spasms of crying, anger and sadness.
DD11 was always a cheerful girl, (except for always being a bit of a liar and very good at emotionally manipulating me) always bright and creative, never had any internet restrictions, has many friends, yet now she bursts into tears at the mention of anything nice!
I don't know what do to help her, she plays Minecraft and scary Roblox games with her online friends she met during lockdown every night, she talks to me about it openly, too.
Please give me suggestions, because I might have to take her to the doctors or something if this keeps happening.

(Note, I'm sure lockdown has something to do with this)
