I only see my Flaws

I know I'm not the only one guilty of this. Whenever I look in the mirror or a photo of myself I see all the little insignificant things I would like to change. I even started thinking about hypothetical situations where I am offered plastic surgery to change my faces and how I would like a nose job, larger eyes, face lift even a forehead reduction it's reached that point of course I never would but I just hate always hating the reflection staring back at me. It's even stopped me from going out with friends because I am so ashamed of the way I look, I used to never care about petty things such as looks. It started when My sister pointed out how pointy my nose was so I became self conscious so I never wanted to be in photos with my head to the side. Then I hated the way I smiled to where I tried my hardest to smile less in front of guys I liked and refuse to smile in photos . Now it's just become an unhealthy obsession where every day I see anther flaw Like how my face is too wide my skin so pale people comment I look sick. My uneven eyebrows. How my face is slightly higher on one side when I smile.my hair that never quite sits right . Now I have started to hate who I am on the inside. How I can't hold a conversation I'm too awkward. I'm boring I can't stand my voice.I think most my friends see me as a inconvenience and view me as stupid. 
It's gotten to where I don't see the point in trying at school with friendships,family etc  
is there any advice you guys can give me?also does anyone feel the same way?
