IIN I feel very behind?

I used to be a lot like you. SO much like you, actually. It all came together with time. Everyone moves at a different pace, and you're still young.

First off, there's absolutely nothing wrong with not having kids or needing help on certain things from your parents at 19. Very few people are fully independent at that age with absolutely no help from anyone. I got my driver's license two months before I turned 18 and got my first real job at 19. I was very nervous about driving, but found out that it's mostly common sense and that as long as you know how to follow traffic rules and pay attention to your surroundings, it's pretty simple. It's very nerve wracking at first, and that's okay and very normal. My first job was at 19 and was your average first job, and I did fine with that too. Just do what you're told, be honest, and do the best job you can do. Fear really makes us blow some of these things way out of proportion and seem much scarier than they really are.

I am 24 and still improving my social skills every day. As someone who was incredibly socially awkward and had crippling shyness as a teenager, it's been a work in progress, but I think I've done very well. That will also come with time, building your confidence by doing positive things for yourself and finding success in them, and practice.

I was also thought to have Asperger's syndrome and was misdiagnosed, and this misdiagnosis caused me to be put on medications that did nothing but serious harm for me, so I would be careful with that. Not that your experience is going to be the same as mine, but that is just my experience. I think we all have our idiosyncrasies and progress at our own levels, and there's nothing at all that strikes me as abnormal about what you've described. You sound like a late bloomer like I was, which isn't really a bad thing because you get to watch your peers go through things you haven't reached yet and learn from their successes and mistakes, which to me better prepares you.
