So she's saying on the one hand, sideline people who are negative and draining - basically, only give time to the positive polly brigade.
BUT if you're ringing your friend, start off by telling them you're upset/feeling crappy. Surely if they took her advice, they'd then sideline YOU because you're not all positive and you're sucking the life out of them.
She's just a big bag of shite, this one. Hasn't a bleeping clue about anything! Who is listening to her advice about anything, she's a bleeping hairdresser. All power to hairdressers but she needs to just be giving out advice on hair. I don't give psychology tips on my Instagram page because I'm not trained in it. I also don't give advice about mortgages or hedge funds for the same reason. Why is this shite tolerated?!
