>>29620139tl;dr for the rest of the post: Please go cold turkey and never look back, anon.
Ex-/akbg/ regular unicorn here. Started following idols in the '00s, and started following daily activities back when Momoiro Clover had daily concerts and someone uploaded them to youtube. Way back before Akari left and they changed their name to Momoiro Clover Z. Before the earthquake.
The sheer amount of content produced by the 48 group eventually led me to focus my attention on it. There's several subgroups, each one with tens of members and at least a couple of TV or internet shows a week, PLUS guaranteed daily concerts. Each group has its own theater. And then they started livestreaming when SHOWROOM (where Kaguya Luna, incidentally, also ended up streaming the most) came about.
So I watched like 10+ shows every week and a bunch of concerts, certainly every graduation concert. When SHOWROOM started, I watched the streams of all my favorite members. I even went on to make subs for one dorama entirely on my own, and another one together with other anons from /akbg/. Subbed some AKB and HKT variety too. Clearly, I was a full on NEET living off savings back then. Spent like 8 years on that until I had no way to pay the mortgage and had to go back to wageslaving, in 2019.
I even spent money voting in the sosenkyo, until one of the girls I voted for scandaled because she was a filthy whore. So I changed oshi (quite easy with tens of members per group, though it did still hurt) and never voted again. But I did, for example, donate through SHOWROOM. The girl who I donated the most to, ended up scandaling as well. In fact, at least 5 of the oshi I had throughout the 5-10 years I followed them scandaled. Maybe I just had the shittiest of luck, or maybe I have a whore detector and I like whores, I don't know. But the burnout did entrench entirely, around I believe 2017.
So I went cold turkey. Replaced 10+ shows a week plus streams plus concerts plus making fan content with grinding MMOs and, eventually, moving to a different city to work. Before covid, I had to commute 1 hour going to work and 2+ hours back, and had (still have) a 10 hour shift. So that was a way to definitely focus on something else.
When covid started, I didn't have to commute any longer, and I could watch streams while working. And while I did start watching vtubers early on (was on virtual youtuber threads since the beginning of Aichan, before the general was even created. I also did stuff like subbing Siro's content through the youtube heroes program, back when I was still a NEET), I only really got into them with Hololive during the start of the pandemic. Via Pekora. Because of the promises the "idol" title offer.
I'm still working and grinding vidya though. And reading manga and some literature. And I don't follow 3DPD idols any longer, thank god - while I was gone, there was a rape scandal that completely killed the franchise's momentum.
Go cold turkey, anon. It's the only way.
