Removing blockages

I've been trying to manifest a few things for a while now and at the start, I was able to manifest specific things easily. I don't doubt the law works. But now these things have been become more difficult and confusing to manifest. I'm not quite sure if i'm overthinking things or what the underlying blockage or resistance is.

I'm trying to affirm that I already have it and I also try not to ask where is it so much, but I keep running into that problem. And then the circumstances, I'm trying not to be like oh this is how things are and it's going to get worse, but I don't quite remember when things were unfavourable for me, how I got out of it.

For example, I've been having issues with getting a job and I'm trying to improve them, but I keep looking at the circumstance and just not quite grasping what I should do. I recognise that it is undesirable and that things can change and be better and then i affirm for that but i keep running into mental blockages.

To an extent I also know some of the blockages and I'm trying to work on them but there are blockages which I can't figure out and I don't know how to remove them

And I'm not sure how to deal with, oh i'm affirming therefore i don't have it.
