Hi everyone,

I know there's been a few 'should I quit' posts on here but I'd really appreciate your advice.
I'm coming to the end of my 2nd year of PhD and I've just passed my APR.
I've had some doubts about being good enough for PhD from the beginning. I guess I didn't enter into PhD for the reasons most do. I qualified as a teacher in 2017 and with no jobs in my region, especially in my subjects, I thought an education based PhD related to my subjects might help in the interim. However, I am miserable.
I have an awesome supervisor who is extremely supportive but I feel they are supportive to the point of not telling me the truth about my abilities and the amount I have achieved to date.
Working with schools and teachers is really difficult. To date, I am nowhere near the amount of data I need. This was brought up during my APR and one member of the panel was very concerned that I wouldn't get enough done in time. I got a by-ball at APR because I lost my lifelong best friend to suicide back in March and have been having a hard time coping with it.
In light of the recent tragedy, I'm again questioning why I keep doing this, if I don't enjoy it. I'm not convinced about my topic because it has had to be expanded - I feel like it's now very wishy washy and I don't see it ever making any difference.

I think I might be happier if I quit but I feel so guilty. Guilty for my amazing supervisor and for my participants who have also been very supportive and given up their time to get involved.
I'm also afraid to quit. Would it look bad to a future potential employer? Would schools be put off employing me if they knew I had let others schools down by quitting my study?
Would quitting now be a huge mistake?
