I was actually raised to say only "nice" things and I think it's extremely unhealthy.
So having someone tell me to stop keeping things inside and to say what I think was a huge life changer. By saying what you think you don't keep negative for as long so in long term it actually works out better. I might not say everything I think and feel to the strangers but I have people I can vent to without judgement.
Glad to see you're back :)
