Some people make it look easy, and some people definitely have better support and healthier adult role models than others. But there's a lot of changes going on when we transition from childhood to adulthood, finding our own identity, launching from the nest, etc - so I think it's pretty commonplace for people to identify with that transition being difficult, especially in retrospect. I can't actually think of anyone who I think would say "Pfft, my teenage years were a breeze!"
Is it easier to go through that process without having to deal with neglect or abuse? Sure. But it's "easier", rather than "easy".
You've started a couple of threads now (this and the barometer one) where you seem to be reflecting on those years, and what's normal, good, bad, easy/difficult...
Confronting my abuse, how "abnormal" that experience was, and how much damage it did, is an ongoing process, and incredibly painful. And over and over again, I've had to check in and (almost stupidly!) had to ask, "Was that bad?" The answer is yes. If you were abused as a child, that's bad.
Child abuse sets you up for all sorts of personality, emotional, behavioural, and mental health problems as an adult. If your primary caregivers didn't meet your basic needs as a child (which includes things like love and security), we don't learn all sorts of key things, like identifying and regulating our emotions, developing a stable sense of self, having healthy relationships with healthy boundaries. And although that might sound like fluffy psycho-speak, that's a big deal. If you've never been taught about what healthy, trusting, safe, loving relationships look like, there's nothing "innate" about being able to develop those sorts of relationships later in life. That's a pretty big deal, and it's just the tip of the iceberg.
So if you were abused, that's really bad. Like, really bad. It's not "normal". It's not okay. It requires healing. It means we have to learn about reparenting ourselves (with no good role models to learn from) from scratch.
And if you're suffering now? If you're having to heal from that? That's justified. I don't need to compare your trauma with anyone elses to be able to tell you that if you were abused as a child, that's really bad, and your suffering is justified.
Confronting that, accepting that? For me, that's still a work in progress.
