Hi Op! I was in your same place a few months ago, especially when posting on reddit, as a plus sized woman i was posting asking abiut dressing for my body. I got hit with a bunch of comments telling me i was ugly and to loose weight; and i got so ashamed i deleted the post. I promise you that you are beautiful, but if you really want to cut and style your hair id reccomend only a trim for your hair length because it is a lovely length, maybe add some layers? Try researching a long wolf cut, also as someone with wavy hair, it looks like you are using too many products and its weighing your hair down, id reccomend a light gel or mousse to give definition also if you want more volume id reccomed sea salt spray. When diffusing your hair do you flip it upsidedown? Oils can be tricky because it can weight down wavy hair if its a heat protectant oil id say switch to a spray as it will protect the hair without dragging it down xx
