Trying to make improvements

I feel like I'm getting suffocated by everything I'm trying, and failing to accomplish. I have this image in my head of what I want, I start to work towards it, and then I can't bring myself to finish it. It's like I'm hitting this invisible wall that I'm creating for myself, but I can't figure out how to get to the other side of it.

I know all my post are fucking bummer hour. This is honestly just the only place I can express my thoughts without the fear that somebody in my life will be worried or confront me about it.
