This all depends. Are we talking about the Erikson model of life stages? If so, I’d say that I miss Intimacy vs Isolation.
Also known as young adulthood.
I know that I’m not an old adult by any means, but I feel like I’m crouched right on the edge of middle age.
Though I had a horrific and extremely mentally and emotionally toxic relationship in my early 20s, so maybe leaving that behind isn’t so bad. That relationship also destroyed chances of future ones.
It added itself to the trauma I was already dealing with.
I see myself as damaged and broken goods now. So, while I teeter back and forth over wanting a relationship, part of me thinks I don’t really deserve one because of all that’s happened.
If we’re not talking about such stages though, I would say I miss the period between late adolescence and young adulthood. I absolutely hated high school, but I loved going to college. Of course, many things must come to an end, but my early college career suffered a blow that it never recovered from.
Despite what I tried.
Once I withdrew from my first college, my attempts to return were half hearted at best. I no longer had a desire to go at all. My motivation seemingly evaporated.
Do I miss it? Sometimes.
Do I miss anything else? I lost someone vital to my life and sense of self… and that resulting in everything else that’s happened to date.
It’s close to twenty years since that happened, and I’m still hurting.
I hurt more over the loss than college by far. So, I suppose that would be the phase I miss. The phase where I felt the most loved and most secure in my life. It was all gone so suddenly.
I still look back on how I thought my life would be at this point, and what my reality is now…
I don’t know what to say really. In some ways, it’s not bad, but in others?
Well…
I’ll let you fill in the blanks.
