Thank you for providing images along with your question. The pointy bump you are concerned about may be cartilage or bone. To know for sure, I recommend scheduling an in-person consultation with a reputable board-certified facial plastic surgeon, particularly one with a strong rhinoplasty...
If you could benefit from a rhinoplasty I’m sure you can find a surgeon who will take care of you. But every case is different. You mention body dysmorphia but that is a very vague statement
It can be done with only tipplasty with closed approach if you want natural result. I agree with you about hanging columella is the most problem of your nose
