I know you think you know them OP, but I can guarantee there is more to them than what you see. They may well envy you
I work in a team that sees people daily who are on the verge of suicide. You'd b surprised how many appear on the outside to have perfect lives. Most people wouldn't have a clue where they r at with their mental health or why. There is domestic violence, trauma, depression, PTSD, insomnia, terminal illness, bereavement, relationship probs, financial problems. So so so so much happens behind closed doors. Very rarely.do.people.show to.others their true selves, their pain and their suffering. We often only see the money, the 'happy family', the outward displays of perfection.
I had very close family friends. Our children grew up together. The wife was stunning - clever, pretty, gorgeous clothes..... her husband was equally wonderful. Both had great jobs, holidays. Their kids are gorgeous, clever, well behaved. I couldn't believe it when they announced they were divorcing. They seemed so perfect for each other, so happy, so sorted. But so much had been happening behind closed doors that I had no clue about.
Focus on you, your family and on the love between you. That's what is most important. Stop envying people you really don't know as well as you think you do.
And even if there are people out there who seem to have it all - who cares. Focus on you and your own family. That's what really matters.
