<human>: I want and *need* to lose weight, but I can't muster up the incentive because I just don't see myself as being as fat as I am.

I'm 21F, 5'6 (167cm) and 224lbs (102kg). A size 18 UK, 16 US. I'm very pearshaped, with sizeable boobs, and I'm in proportion all over. An average pear-shape, just stretched out. 

The big problem is, when I look in a full length mirror, I don't see myself as awfully fat. I see nice curves - boobs and hips, nipped in waist. Because I think my body's alright, I don't have the incentive to lose weight. I'm lazy and exercise is a means to an end for me, I don't enjoy it at all. Once I'm at the gym, it's fine, but more often than not I can't motivate myself to actually get up and go. I eat primal/paleo and count calories, but every so often I have a huge pig-out day and I always end up thinking "well, it's not so bad, I could look worse."

I know I need to lose weight - I don't enjoy chub rub on my thighs in the summer, my back hurts a lot of the time, I have very little stamina and I just don't want to be the fat kid any more. 

But each time I feel really serious about losing weight, I always end up thinking "well... it's not THAT bad. I'm alright." and that's that.

It's not that I want to suddenly start hating my body. I need to muster up the motivation to get really serious about this and not give up after a few weeks.

Can you condense the text into a few key points?
