You use a lot of assumptions. May have..you don't know that. Everyone goes through hard times and people do experience seasons of mild depression. As a person who has experienced serious depression first hand and was unable to get out of bed, I can tell you Taemin isn't as mentally ill as people seem to think. He wouldn't be able to dance at all. He would always seem tired like Jonghyun used. Jonghyun would sit a lot during his concerts because depression really really drains your energy. He always had a chair. In one concert the man had a blanket. It's the way the mind is when depressed. That's why many depressed people sleep a lot and have strange sleep patterns. I used to sleep until noon. Jonghyun used to sleep during the day. If Taemin was taking 6-8 pills as you claim, how did he have all that energy to dance? Depression medication alters your state. I was prescribed wellbutrin but I stopped after one day and decided that was it. I had to overcome this. It's no joke. I hate it when people use depression as a cop out. It's no joke. When I was sick, getting out of bed felt like someone had a huge rock on my shoulder. I had no energy. There was also thst SM show where Jonghyun was dancing and he almost passed out. That depression medication does that to you. Sorry but I don't agree with this assumption.
The Military exempts depressed people because they are practically "useless". He wouldn't even have the energy to do social work.
This may seem strange but he needed that chair. He worked it with the song but he needed it.
Being alone on stage really drains a depressed person. At least with SHINee concerts, he would absorb strength from them.
