Duke, life is not fair, and it never will be.
You are on the spectrum, and you don't have the most optimistic way to look into the world. You also have moods that can make it hard to connect with people on top of that.
So, life is hard. Making friends will be hard. It's not impossible though.
I think it is time you start to take serious where life is hard for you. Whining for a while is OK. But then it is time to make an inventory of good and bad things. And also a list of what you need help with, and what kind of help.
Stopping to whine doesn't mean you should stop taking your problems serious. It means that you should stop wallowing in feeling sorry, and take the problems really serious. Take them serious and try to find the support you need.
There will be support there to help students. Go there, lay your cards on the table. You are on the spectrum. You have sensory issues. You find it hard to connect with people. You want to have some connections with people. You can have moments of rage and lashing out. You need to get some grip on that. Investigate what you need. And go for it. Don't be ashamed to ask for help.
It will never be easy. But, don't let that keep you from trying.
And do bring your expectations down to something realistic. Making friends the first week would be a miracle. Give it time, and do make an effort.
