Lack of passion from the beginning of my PhD
I'm afraid to say that I think you've worked this one out for yourself.

Completing a PhD requires passion and determination to get over the finish line. I remember someone once saying to me that they had done two PhDs but hadn't written either up... So they had actually not done a PhD at all. The point is that in a lot of ways, the writing up and creating a thesis is the hardest part because it requires so much time, energy, and dedication. If you don't feel like you have that for your subject then I would really consider your options.

As for your family (and friends)- they don't love you because you're on a PhD programme, that doesn't even come into it. More than anything in this world, they want you to be happy doing what makes you happy and I'm sure if they read your post just now they would tell you to stop and find something you really want to do.

Right now, it may be best to have a sit down with your supervisor and discuss how you're feeling and see if there is a way for you both to move forward that suits you both.
