I’ve quit my job and I’m going to spend until next winter traveling alone, what is the most important items I need?

As the title say, I (33 F) quit my job and I’m going to spend till October traveling the lake distract/dales/moors.

I’m an experienced hiker and I’ve done many multi day hikes but not alone. I know the basics i need like tent etc, but I’ve never camped alone as woman and I am planning on staying at proper campsites/hostels.

I’ve look at many different kit lists but what is really necessary and what is just extra weight.?

I don’t know is this matters, but I’m 5’1 and 7st 11 so I think I can only have 20-25kg at most if I’m doing it for months

Il be leaving March 30th

Thanks in advance please feed me your knowledge .
