What advice would you give someone who has been self isolating for years and finally wants to make a change?

I’ve been self isolating for the last 3 years and I want to make a change but I’m not sure how. Just for a bit about myself I’m a really shy and introverted 17m who was homeschooled which meant I didn’t have to push myself out of my comfort zone and talk to people and because I didn’t have to I was stupid and didn’t. Because of this I have zero social skills which makes it difficult to have a normal conversation that doesn’t feel forced. And I know to improve my current situation I need to actually get out but I’m not quite sure how. I live in a small city (less than 40k so not tiny but not very big) so it seems difficult to find social opportunities and even when I do find them I can’t push myself for some reason. The only current place I talk to people outside of my family is work.
