Hello LuCkY and welcome to the board.
Have you got any profile and/or oblique shots? I don't see anything wrong with your nose in those pictures, it's a large(ish) nose but it suits your face, in my opinion.
Do you have a bump in your bridge? If so maybe getting rid of the bump would make all the difference. I don't see anything wrong with your tip, it doesn't seem to droop and it has a nice shape to it. Maybe filing down the bump (if you do have one) would be enough to make you feel better about your appearance. This is just my opinion based on the pix that you've posted.
I know what you mean about your nose affecting your confidence, if you feel that strongly about it then go for it.
It is true that you can't trust everything you read on cosmetic surgery boards, but we are all adults here and none of us seem particularly gullable. Most of us are able to see through individuals who are just interested in plugging products and/or clinics/surgeons endlessly. I have been on this board since day one and I think everyone here is genuine, as well as very caring and supportive
Unfortunately, the same can't be said about other boards
but that's a different story.
