please someone find a solution (very werid)

Hello guys.. hance I dont want to waste your time by explaining the whole story so let me get to the point..

I`ve been struggling with anxiety issues for past 5 years so far, I used to have pure OCD (repeatively thinking, ruminating about things insie my head)..

also had other assosiative problems such as physical symptoms, anger, irritation e.t.c..

after starting meditation and regulating my life with both productivity and discipline now I feel lot better (also taking appropirate medicines consulted by Psychiatrist)..

Now I get weird and completely disgusting feelings such as humiliation, upset, agression e.t.c..

whenever I encounter flickering of lights (either tubelights or LED, none of them fixed my problem)..

I`m not seeking for psychological related solution, just tell me how to fix and what is the cause of flickering of lights??

Ive even tried by plugging into voltage regulator, none of them were worked..

Can I able to fix this issue by connecting lights from backup (UPS) source instead of direct electricity??..

Please guys, I need to completely eliminate flickering issues

BTW flickering happens everywhere in both my house and other places (college, tutorial, hotel e.t.c..)

atleast fixing this issue over my house will be lot helpful!!
