Body dysmorphia - is what I'm seeing real?

Hi there,

I'm a 23 year old lad and suffer from body dysmorphia. Again, I've just found myself spending 3 hours looking in the mirror and taking photos in different lighting to see if my flaws will go away. Just like always it isn't. 

It's gone from excessive worry about my hair, to my forehead, to my chin and now it's currently on my eyes, where I hate the way my lower eyelids look, which sounds crazy, but spending hours trying to find what the perfect lower eyelids on a male looks like isn't right and currently putting me off from doing my dissertation. 

I haven't mentioned the eyelid thing to anyone but despite reassurance on the other things I literally can only believe what I'm seeing. This has been going on for years now and seriously affected everything from uni to relationships to jobs and I need to do something about it, as I've also considered surgery for all of these flaws.

Despite attention off girls, I will always make up an excuse for it such as 'maybe they only saw me in good lighting' or 'maybe the only reason my eyes didn't look weird was because I was wearing a hat' - stupid stuff like that.

Can anyone please tell me what I can do about this and am I really as bad as I'm seeing in the mirror?

Thank you very much for taking the time to read this
