This is how I feel so much of the time. I am 44 years old and have always felt like this. I am in my third long term relationship.
I had an abusive childhood at the hands of a severely mentally ill mother after my father died and eventually ended up being brought up my grandmother against my grandfathers wishes.
So I can absolutely see where these feeling come from, insecurity, no sense of belonging, feeling irrelevant etc all stem from my childhood.
However, it doesn't mean that I'm not overlooked in adult life, I suspect I create my life subconsciously to be that way.
Let me just give this weekends examples.... out on Friday night at a party, I was the driver. The photo's put on social media afterwards excluded my name and I wasn't tagged in them. I was the only one forgotten. I have paid for big family meals before and all the photo's afterwards excluded me from the comments or the tags too.
Saturday, I am the last to know who is home for dinner and yet I do all the food shopping and cooking. I have to fight everyday to find out from my step kids and my partner to find out who I am shopping and cooking for and eyes are rolled when I keep asking as if I am being very unreasonable.
Saturday night I arrange a catch up with a friend, she was supposed to visit me, but said she couldn't as she had her 17 year old daughters dinner to cook. I cooked for 5 people and had to travel to her as I nearly always do. Obviously no acknowledgement that I might have had a lot to do too. I then spent the entire evening with her daughter which changed the dynamic from an adult evening.
Yesterday we were with partners parents, they kept on and on about hard working someone in the family is (this person works 15 hours per week with no responsibilities) and yet my full time job, studying, sporting achievements and looking after their grandchildren full time is apparently not worthy of acknowledgement and hasn't been acknowledged once in ten years by them.
I read this back and I sound like a right old whinger, I know.
At the party on Friday, I was talking to someone, they get interrupted by someone they know and I am literally left standing there with this person's back to me. This often happens, where I am literally just left standing alone.
It's just the constant little things and I honestly don't know how to stop it.
I am a quiet person so I can see how it happens. I don't have a lot to say and when I do, I speak at a fairly low volume. I think subconsciously I try and not be noticed, hate being the centre of attention and then get upset when i'm not noticed or acknowledged!
Honestly, can anyone else relate to feeling like this, how do you cope?
