I was trying to remember when I started, so that post was a good reminder. I'm in month 5, with a month of that off due to holidays and some work stuff.
I'm not finding it easy, everyone keeps telling me not to run into it, just take time. E.g. I practice chord changes nice and steady and slowly but then in a song situation, it's all too quick and falls apart. Building in strumming patterns just throws the whole thing out of the window.
But it's better every month, without doubt. I'm going to practice some scales I think, and keep putting in minutes every day to the chord changes, which are really slow going at the moment.
I guess it's a case of getting the balance right between pushing yourself to improve but also making sure you're enjoying what you're learning.
When I started off I was pretty much only interested in riff based rock and early blues stuff so I only really learned to play one note at a time and proper chords didn't come into it for me until almost a year in. Honestly, six months down the line I was still pretty much entirely tone deaf and my guitar only got tuned when my mate came over. Must have done my parents fucking heads in. So in that regard I'd say you're probably progressing a lot quicker than you realise.
My advice with open chord changes would be to find songs you like with similar chord shapes (E/ Am or G/ C/ F) and practice those until muscle memory sets in.
With barre chords it's just about finding a combination of finger positioning and pressure which is comfortable for you. I had to learn the Hendrix way of doing it (thumb on the 6th string) because I had a pretty fucked up left wrist. It doesn't work for everyone but everyone's hands are different.
Strumming patterns can be tricky but that will just click eventually. If you're playing along to some music I'd just focus on the chord changes for now and slow the strumming down so you're just hitting the chord on the beat or even just once when it changes to the next chord.
I'm (finally) learning to drive at the moment and it's reminded me quite a bit of when I started to learn guitar or drums years ago. It's quite daunting because there are all these little processes that go into it and it's easy for it to all fall apart when you focus too hard or mess one aspect up.
But like I said, muscle memory is what it's all about. Once you get to that point of not having to actively think about what you're doing, that's when it gets exciting and there's honestly no other feeling like it.
Keep at it but make sure you're enjoying what you're learning. If it gets frustrating, try and learn something else and then come back to it later. Countless times I've tried to learn some new technique or whatever else for an hour or two and my stupid fingers don't seem to want to do it. Then I'll put the thing down and try again the next day and I get it right first time.
YouTube was honestly a god send, even moreso now. There are pretty much endless choices for lessons on any song/ technique/ whatever else you could want to learn.
Anyway, a lot of waffle and I doubt any of it is actually of any use but I like hearing about people learning to play instruments because everyone does it differently and it reminds me of when I was younger. You'll be so far ahead of where you are now in no time and you'll still be learning and improving.
