YABU. You have NO idea what is going on in someone else's life.
I agree with previous posters that it should not be a competition. Is a person with 2 kids, not allowed to complain to people with 3 kids, because the person with 3 kids obviously has a harder life? Is a child free person not allowed to complain about being tired, even though they may have a stressful job, long hours, a mean boss, bitchy colleagues, and only one income because they are single, making them struggle financially too? Is someone who is 3 stone overweight not allowed to complain to anyone who is 4 stone overweight, about their weight making them unhappy?
I hate this competitive 'my life's harder than yours' bullshit.
I was going through a very rough time in my life some 11-12 years ago, for many reasons that I won't go into in great detail, (but it involved bereavement, illness of my DH, my kids having problems at school, health issues of my own, big financial problems, huge issues at work that were making me dread going into work, and problems with vile neighbours making our life hell.)
Yet I never complained about anything. It was no-one else's business or burden. On a course I went on, this woman (about 5 years older than me) was a single mother of 3 children, and she was in a private rent house, and struggling financially.
I had a husband, an (owned) house in a little cul-de-sac, and a car which I needed for work, and for some reason she took an instant disliking to me, and kept spouting shit like 'I didn't know what it was like for people like her..' and similar bollocks about the 'privileged blondie' up the corner in her 'fancy house.' That was the tip of the iceberg. She assumed I had a precious, privileged life because I never complained - unlike HER who never stopped complaining, like she was the most hard-done-by person in the country.
I wanted to knock her out, as she had no CLUE about the problems I was facing in my life at that time, and what I was dealing with in my life. I changed the day that I attended the course (to another class running the same course,) as I couldn't stand being near her.
Upshot is, don't assume that if someone is not sitting there moaning and bitching all day, that they have a blessed life. It's rude and presumptuous, and makes you look arrogant and foolish.
I have to add that thankfully, my life is much better now (and my family's too,) we are not in that neighbourhood anymore, our finances are much healthier, and I am not in the same job. But we went through a tough time as a family in the second half of late noughties.
@Tired78 you sound angry and bitter and resentful. And it's very unfair to resent someone else, and assume they have a much easier life than you. As I said, you don't know what is actually going on in other peoples lives. Maybe focus on your own life and what you can do to change things you are unhappy with, rather than resenting others, who appear to have a better/easier life.
