When I built my current PC, I was the same. I was bricking every moment and all the wires looked confusing as hell. I was tempted to get my cousin to build it for me as he built my brothers, but after my brother had issues with his PC, I decided to not trust him and do the build myself.
I followed a youtube video step by step and paused at every stage, while also looking at the manuals which come with the products. Honestly, it's pretty straight forward to do and feels very rewarding once it's up and running. I did have a time when I started to get frustrated with it but I had a friend on whatapp that was able to guide me through it. In your case, you just need to ask here.
