Leaving parent's home as an autist

I finally found a job so I am going to move out of my parents' house soon, in order to live in the large city where the job is located with my gf. I should be happy about finally becoming independent and being able to see her every day, however I only feel dread about the transition, the lack of free time for my interests (probably intensified due to my shit executive functioning) and the fact that I will miss my family. How did you handle such a transition?
