I think I posted this in the wrong category so will get the old one deleted...sorry :(
I feel embarrassed writing this down, but I don't feel I can really tell anyone how I really feel. I strongly dislike my father's new girlfriend and I think it's because I am feeling somewhat envious or jealous, and also very embarrassed. She's way younger than him, and just 3 years older than I am and I feel incredibly awkward about the whole thing.
For context: I grew up with my father, because my mother left when I was quite young and I barely had any contact with her growing up. I appreciate that this can't have been easy for him either, but as a consequence I have always been quite accustomed to sharing his attention whenever he was going out with someone new. It really wasn't great but I got used to it. The taunts from my friends about his escapates were the worst to be fair, but I usually got on with the women.
I'm not sure why it's worse this time. I think it's because she is so young and almost my age, and maybe also because I have had a lot going on in my own life lately, but I feel so upset by it all. All I really want is to tell him everything and just cry, but I feel like I can't and I am so worried about being replaced. I know that I sound mental writing this which is why I don't think I can tell someone. Is this totally nuts or can someone understand me to a degree? I'm really dreading the next few days
