Tooru Oikawa

TW FOR ANXIETY, KNEE INJURY, SUBMECHNOPHOBIA, SELF HARM, CHILD NEGLECT AND FAKENESS

-Medium pain tolerance. He usually plays it up for dramatics.

-He actually has a pretty good immune system but that all goes down the drain when he overworks himself. He'll get a fever from pulling on too many late-night training or studying sessions. He tries to play off that he's sick, will not admit it. Iwaizumi will put his foot down when after school practice rolls around and will either tell Oikawa to go home or will drag him there himself.

-Not emetophobic but hates making messes. Throwing up on himself will make him cry or extremely distressed because of the mess.

-Horrible travel sickness. Cars, trains, buses, planes or boats he will be sick.

-He gets migraines after watching too many videos of other teams on his computer. Or just screens in general for too long.

-Submechanophobia, the fear of sunken man made objects. He figured it out when he was in middle school and his grade went to a museum. Seeing a model of a sunken plane made him dizzy, nauseous and very uncomfortable. When they got home, Iwa and him googled the fear.

It is a really rare phobia so some people thought he was joking or being dramatic and would send him pictures of sunken ships and planes just to see his reaction; only to feel somewhat guilty when he had to ask a friend to get rid of the picture while he took a seat.

-He also is terrified of disappointing people, this often leads to him overworking himself.

-He has anxiety, was diagnosed with it at age 8. He has it under control but everyone has bad days.

-Oikawa was diagnosed with Borderline Personality Disorder in his last year of high school, after living with the not diagnosed symptoms of horrible self image, mood swings,and emptiness since his nine. He was horrible at keeping friends with Iwaizumi being his only friend until high school. His doctors and psychologist thought the symptoms would fade with age and maturity. Unfortunately they did not and an incident where Oikawa was rushed to the emergency room lead to the final diagnosis. He spent a week in a psychiatric hospital. He never mentions it and the only people who know about the event are the seijoh thrid years, the coach and his parents. The only signs are the faded scars sometimes visible on Oikawa's hips. 

-He has spent years perfecting his facade. His walls are built up so high Iwaizumi is the only one that can see through them. He has gotten scarily good at hiding his true feelings behind a mask of "iwa-chan!!" "ow that hurt" "because i'm the best" plus the whining all of the time.

-horrible insomniac. runs of caffeine and determination. has a minimum 10 hours of sleep a week.

-During his last year of middle school he tore his acl. He called Iwaizumi and was brought to the hospital by Iwaizumi's mother. He couldn't play volleyball for the first couple of months of his first year of highschool. He hated the recovery period the most.

I headcanon that Oikawa's parents are never home. They work most days and don't get home til late. Leaving Oikawa at home alone pretty much 24/7. It's been this way since his sister moved out when he was 12. Due to this Oikawa actually knows how to cook, surprisingly good. Sometimes they leave on business trips with only a note on the fridge. They were overseas when he tore his acl and got home a week after the incident. He spent most of that time at the Iwaizumi household. When his parents did come home they told him he should have been more careful and made no moves to comfort or console him. They just went into their home office and started working on stuff for the next day. It was Oikawa sister, Chihiro, who bought him the knee brace after the surgery bandages came off because his parents were too busy to buy one. Chihiro is also the one that buys his anti-depressants.
