Dealing with parents being an autistic adult

I'd like to ask for advice regarding behavior that could make my parents feel more secure about me as well as cared for. I am a college student living in another city and have had many problems with alcohol last year due to a depression crisis that hit me. They got really worried as well as really really upset with me and i cant stop feelling guilty about it.

If there are any parents of autistic people here, please feel free to share things that you feel your son/daughter could do to make you feel more at ease and loved.
