Cosmetic Surgery

Q: I'm turning 19 this year and I wanna know whether it's permissible for me to attempt facial surgery?

Backstory: Since I was a little girl, I've always been insecure about the way i look. I clearly remember people commenting about my face. What's wrong with my face? It's asymmetrical. More specifically, the things that really bothers me are my eyes and nose. My eyes are not symmetrical as one is higher than the other/not leveled and one's smaller than the other. I was born with one monolid and one double eyelid. I remember when i was little, my friend said that one of my eye is smaller than the other and then continuing doing a facial expression by squinting one of her eye so that it would resemble me. That happened when i was around 10. It left a huge mark on me. And then there's my nose. I'd describe my nose as a nose that has a weak nose bridge/no bulbous tip and if you look at it from a downward angle, it looks like a hemisphere rather than a triangle just like how other people have. When i was 14, my friends were talking about my nose and asking questions about it which made me insecure but i didn't show it, she later on touched my nose to feel it and she said that i don't have a 'bone' on my nose bridge/tip of my nose and she concluded that's why my nose is shapeless/big. Other people have made their criticism on it, telling me that it's big, weird and made it seem as abnormal to them.

Those two things really made me feel so self-conscious about myself. I hate going out and even wearing the hijab because it somehow accentuates the face and mine is so asymmetrical. it somehow led to my depression as i was diagnosed with the mental condition when i was 15 and took prescriptions up until now. so, what's your opinion on my case? Can i do surgery on the parts that i mentioned? 

Q: I have a question regarding cosmetic procedures... I know they are not allowed in Islam, however are they allowed when somebody's appearance has changed due to heavy black magic/Jinn? My skin has become very dark on my face, patches of black marks everywhere, hair loss, loss of so much weight due to constantly vomiting (no medical cause) features have become so manly due to this. I'm only 26 years of age but even my teeth are breaking. I've had 5 teeth which have been broken by just chewing normal food in one year (again no medical cause) and its not because i ate too many sweets. I don't want to do this for cosmetic reasons it's just black magic has already destroyed my appearance so much to the extent I'm scared my husband will desire and go to other women. Even me and my husband have sihr of seperation.. my niyat for thinking of cosmetic surgery is just to rectify what has been changed due to the sihr. Not change anything in any other way but just rectify to it's original state. 

Q: I have a very wide nose. Whenever I look at my nose I feel stressed and low confidence when meeting with people. My intention is not to look beautiful but I just want to get confidence. Can I undergo nose surgery to make my nose little smaller.

Q: My question is regarding septo-rhinoplasty. I have a deviated septum and outwardly the left nasal bone is wider then the right, giving an unpleasant appearance to the left side of the nose. This causes psychological distress and the deviated septum causes left side to be blocked, i.e there isn't full flow of air at certain times. The doctor said he will correct the deviation and will make the left nasal wide making it more natural and even. Along with this the nose will be defined and reduced in size in very conservative manner. I believe when they reduce left nasal bone to balance with the rest of face and make it look normal it would need to be defined to give normal appearance. Is it permissible?
