I think a lot of what he says and does is an act because he doesn't actually know himself. This is evident in the way that he constantly contradicts himself in his stories. I also don't think Melvin is particularly happy with his lot in life and is desperate to be 'someone' and to have 'hunners' of adoring fans. He loves the idea of being something special, that needs to be cared for and this is why he mentions his IBS, flu, feeling sick etc.... for the attention. The dopamine hit he gets from the likes and comments is immense, and he must spend most of his spare time glued to his phone checking for mentions so he can repost them on his stories to prove how popular he is (both to himself and to his followers). On instagram he can be 'someone' and plays up to this, pretending to be a sassy queen with attitude to rival RuPaul and tries his best to create a lifestyle. At the same time, how people perceive him is of immense importance, so in a public setting, he brings to the fore the part of his personality that fits in with his surroundings. We all do this to an extent, but with Melvin it is quite dramatic. As Kaydeelaydee says, it's all Melvin, it just depends on the circumstance.
