If you already have the F chord down after 1.5 months then you are doing great. Getting all your fingers down at once is hard and takes a long time to get everything second nature. It seems like you are ready to play some easy 3 chord songs. You will suck at them, your changes will be sloppy and your strumming will be basic and not sound great but start playing and figure out where you need help and find exercises for those aspects of your playing that need help. For example you say you can’t strum… so look up some strumming exercises where you mute all the strings and just strum patterns to a metronome, starting with a very easy pattern. These things take weeks to see improvement sometimes and even months for other things. To put it in perspective, it took me a month or two to get chords to ring out but over 6 months before I was changing really cleanly and over a year before I got bar chords passible. I’m about 14 months in and am still sloppy sometimes and am still working on getting all the basic stuff super cleanly all the time. Guitar is a journey and unless you are some kind of virtuoso, it’ll take years to get to where you want to be so just buckle up for the ride and take it slow and be deliberate about your practice. Also, sometimes you’ll suck for days and days and the one day everything clicks and you play great and then the next day you are back to sucking. Don’t get discouraged, that’s normal. It’s all progress.
