one of the reasons mental illness sucks so fucking much is because people around you can literally tell you again and again that they love you, that they think you’re cool and funny, that they support you in every way, that you’re talented or intelligent, and no matter how many times they say it you’ll always cringe and shake your head and say “no, no i’m not, really” but the SECOND someone says one bad thing about you, even just once. You believe it completely.
tbh i love that clip of magnus's petty ass, and i love that he's kinda wary and vulnerable when it comes to relationships. there's such a huuuge difference in age, experience, and power between him and alec that it would be easy for their relationship to feel very boring and unequal with him as the perfectly mature wise sage teaching alec all about love. it's so much more interesting and healthy if they both have flaws and insecurities and moments of immaturity and pettiness.
