Welcome back !
I totally get where you're coming from; the longer you leave it, the harder it is to get started again. It's a kind of guilt thing I guess, but there's actually nothing to feel guilty about.
If I can offer a tip, it's to work like a sloth. It's certainly how I work ! Sometimes, I just haven't got the brainpower to write anything. So I don't, and I don't let myself fret about it. But other times, I've got a buzz on and really feel like writing. So I'll put together two or three posts.
They don't have to get finished; it might be just the text, or an image or two, or sometimes just the idea and a couple of lines to remind me what I wanted to write.
I used to use Word, and store them on my PC until they were fully cooked, but now I tend to just create them as drafts in PeakD (mostly based on templates - the best thing PeakD have done, and a truly slothy way of working !) That way, I've got a backlog of a few things that won't take much effort to finish of and turn into actual posts when I don't feel like writing something from scratch.
Aaaand I just wrote a comment long enough to be a post in it's own right, lol. 😆
