You can totally read manga to comfort yourself BUT mental health is important, if you suffered a trauma you should seek attention from a psychologist, manga can't replace professional attention. Therapy is not something that you have once and you feel better, it might take you months but you should give it a try, don't let your trauma stand there because it'll try to take you down w/time. Good luck (๑•ㅂ•)و✧
Uff...You "feel" like its a comfort thing because it is supposed to be. It would be wierd if you get stressed and anxious out of reading manga.
Why do people always question "am i wierd" NO! You basically are asking if all those who are like you are wierd as well. I am sorry, i dont think I AM WIERD for thinking every sentence like that is an hidden insult.
It isnt weird. Even if you are reading BL, comic, or classic book, reading is a wonderful way to escape from your own thoughts and honestly way healthier than having a destructive coping habit such as harming yourself. But honestly everybody is at least a bit weird and if you meet a “normal” person they just are hiding what they dont want you to see. The important part is finding people in our life that we can be weird together with.
It's normal. It's a hobby you enjoy, so there's nothing wrong with using it as a comfort thing/coping mechanism. I'm the same, whenever I get super stressed or depressed, I often go for BL or yaoi. I told my counselor I read manga to help myself relax and she said that was a good thing. So don't worry about it.

I've been reading manga for over a year now mainly being Yaoi and BL and sometimes shoujo, now l feel like its more of a comfort thing, like I need to read.
I only started reading manga after a traumatic event and although I'm coping better I still find comfort in reading this...
Ive spoken to many friends and even mentioned it in passing with a counsellor and people seem to think its weird...
I can understand that the subject of the manga isn't always sunshine and rainbow and can be sexual but is it odd to find comfort in reading this??
I feel that when I'm reading im able to forget everything in the real world and the pain I suffered, it has helped me a lot, but it seems no one I know thinks its normal, so is it really weird?
