Is It Normal to Struggle This Much with a Dissertation?

I'm in the middle of writing my dissertation, and honestly, it's been a lot harder than I anticipated. Choosing relevant sources, developing a strong argument, and keeping everything academically structured feels overwhelming at times. I've been looking into dissertation writing help, but I'm unsure what kind of support is actually useful and trustworthy. Have any of you used academic guidance, university resources, or other forms of assistance during your dissertation journey? I'm mainly interested in improving my research process and making sure I'm on the right track. I'd love to hear how other students managed this stage of their degree and what helped you stay productive. Any suggestions would be greatly appreciated.
