To begin with I’m not like any Dr. Who fan, it actually took me a while before I got into the whole concept of Doctor Who. Now that I have, I can gladly say, my lack of sleep and binge watching was totally worth it. In the early episodes of the new Dr. Who, I was actually enjoying the Doctor’s “adventures”, but then I started to observe him closer (not physical appearance, but the “vibe” his character was emitting). The Doctor was always trying to fix things, I thought sometimes his happy mood was forced, and that led me to thinking that he was actually sad (well, through how he talked about his race). That led me to the conclusion that the Doctor was going through POST TRAUMATIC STRESS DISORDER.
Before I continue, I would like to point out, that all this is based on my opinion. So, I’m not implying things, but merely stating my observations.
To be clear, PTSD is a health condition that affects a person mentally, and this is caused by witnessing or experiencing a terrifying event- which they may end up having terrifying flashbacks. While observing the Doctor I noticed that whenever the topic of his race comes up or he gets reminded by it, it is very obvious that he gets really sad. It is until later episodes that I found out that he had something to do with the end of his race, and this was during the Time War between his race and that of the Daleks. Also, he seems really cautious about people dying, or Rose dying. Could this be, because he does not want to relive losing someone/people he cares about AGAIN? Maybe. Additionally, he is really insistent on the fact that things have to happen for a reason, I think that is why he really regrets the loss of his race. Oh! By the way, his race BURNT, but he made it clear that it had to happen because the fight with the Daleks was getting intense. Coming back to the Daleks, when the Doctor had a re-encounter with one of the Daleks, he was really mad and he blamed them for losing his race. Just to say, the Doctor is a little bit scary when he gets angry- Yikes! I think he when he saw the Dalek, he had a painful/sad flashback. All this while, his character felt stiff, and he seemed kind of lonely and lost. Trust me, no ordinary person would like to get into as much trouble as the Doctor, but I noticed it’s because he’s trying to fix things (maybe, because for once he wants things to work out).
But alas, the most obvious evidence of his PTSD was in The Empty Child, when he said “Just this once, everybody lives…” He was so happy that people did not end up dying, he looked relieved. I think that his way of addressing his PTSD is by travelling through time and fixing things.
