I did a lot of therapy before I realised autism was an issue for me, and changed and grew through it, so I would say, there's likely to be lots of aspects of yourself you can work on, and that will lessen some of the effects of your autism.
In the end there was only the core of autism left that I couldn't change, which is quite significant, but not all of who you are. Go to groups or classes, or some therapy, read self help books, work on yourself, do voluntary work, paid work, trainings , get qualifications, get work, join a walking group. Though some of this is hard just now, but not all.
You can improve your situation and feel less affected and have some friends, Take one step at a time, and consider that autism is only part of who you are. We know from research that people with autism can and do make attachments to others, plus we develop attachment styles same as everyone does, and we can work on our attachment behaviours if we are insecure, for example we may have got insecure both through not understanding the world so easily, and from people not understanding us, especially parents.
You can work on this to relate better and to feel more secure as a person, and lessen the effects of the difficulties with communication and other issues that autism causes. It's not true to say we are autistic so we can't improve, we are a mix of things, including for me, having big feet and autism which I can't change, but also having an insecure childhood attachment style that has improved through therapy, aswell as getting strategies around things I found difficult in relating to others through self help , through therapy, and through some social practice in settings where I felt safe.
