Hi. I hope my own experience can help you. I have a whole bunch of learning disabilities and very bad anxiety/panic issues. I graduated high school with a 5th grade reading level; and frankly I was pissed. No one should have fallen between the cracks as much as I did.
I got stubborn and angry and I did something about it. I refused to let life just push me down and accept it. It's a bumpy, rocky, uphill climb. But you can do it.
IQ doesn't mean crap. I encourage you to go out there. Walk outside. And be pissed off at everyone who told you that you were not good enough. Now imagine proving them wrong. Let that guide you a bit.
Feel free to PM me if you want to talk. I've been in your shoes. It does 100% get better.
IQ does not define your destiny.
I don't know what my IQ is. Nor do I care what it is.
You sound smart enough to ask for advice. I don't think your IQ is as low. Let's go through some steps. You can type, read, write, use the Internet, figure out how to get on the fedi, realize you have an issue, and you asked for advice. That's more than 99% of people can do. My parents couldn't do what you did.
I was once told a story about an IT worker. They got called by a doctor about their mouse not working. The IT person tries to troubleshoot the issue with no luck. They go over to the Doctor's work station. The Doctor is trash talking them. The IT guy looks at the computer and realizes the issue instantly. The mouse is upside down. (This is a true story)
We are all smart in our own ways. We all have talents and gifts. What can you do well? And if you don't know that answer; ask your friends. Take inventory of yourself.
