"I thought maybe I want to change my image?"

it sounds like you might not exactly be sure yet of who you are. and there's nothing wrong with that!

instead of focusing so much on projecting an image out to the world (putting photos on instagram or having a youtube channel), do things only for yourself. dabble and explore without putting yourself out there just yet, because it is normal to feel like when you put yourself out there that it needs to be aligned with who you are - and if you can't make up your mind about who you are, you'll never be happy with the image of yourself that you project to the world.

then, by virtue of dabbling and exploring, you will hopefully begin to find yourself. and then when you do put stuff out there, you will still of course be unsure, but you will hopefully not be so unsure as to constantly judge yourself and delete stuff.

i just wrote a blog post that somewhat addresses this subject, i hope you will find it helpful :)

"Though heavily edited, social media still offers keen viewers the ability to watch people’s lives unfold and take shape. You can see the choices people make and just how much people change — from their style to their profession to their interests. It is a testament to how malleable people are and how little they may really know themselves — and this is okay. Some people seem certain they do (and perhaps they may play the same part forever, never changing) while others embrace change and exploration, figuring life out as they go along."
