In 2nd year with no friends on my course

As the title says, I'm already in 2nd year of uni with absolutely no friends with anyone on my course. I have friends in societies, sure. But I do chemistry and I regret 1st year so much. I hardly attended lectures, I didn't make an effort to talk to people or include myself in friend groups, I'm autistic and have severe social anxiety. Because of this, I stopped going to uni entirely and did all of my work remote so now the people on my course don't even know who I am. I'm too scared to show up to lectures or seminars alone so I just don't, which buries me further into the pit of having no friends. Sometimes, it makes my course so much harder because I can't just ask my friend how to do a question or answer a problem; I'm just constantly messaging my lecturers, who take weeks to reply.
