Welcome to the forum, @Wonderer, and thanks for sharing your experiences. I’m sorry your diagnosis affected your life so much, but it’s great that you are monitoring your condition and found out before any liver damage had occurred.
There are many factors that go into the decision to start treatment (see here for the main discussion on the forum: Deciding when to start treatment), most importantly whether you want to or not. Within the EASL guidelines, treatment may be considered. Depending on how variable your ALTs are (e.g. if they go above 40IU/mL) it may be recommended.
Hope this helps,
Thomas
