It seems like you are learning at a good speed. Nice.
A lot of people have given advice, so here's mine. Learn to read tablature. I know it's not fancy like real sheet music, but it is not anything to be look down on. Tablature is actually older than standard notation. And guitarists have found very intuitive ways to show their finger movements, and little tricks like hammer-ons and pull-offs.
For instance, in the standard notation of the intro to Redemption Song (a highly recommended starter song, by the way), they don't show the hammer-ons, but if you listen to Bob Marley play it, or better, watch the You-Tube of him playing it solo, you can see the hammer-ons.
Anyhow, keep up the good work!
A guitar can be like your favorite pet when things make you blue. It can love you unconditionally.
I have been playing for a long time. The one warning I would give is regarding GAS (gear acquisition syndrome). It can consume you. Case in point, my man George here:

See, eventually you need a 12-string, then a bass, then an acoustic bass, then a classical guitar, then a Strat, then a Les Paul, then an amp and pedals and multi-effects processor, then a four-track, then a 24-track digital recorder... If you plan to have children, be sure to buy this stuff first! LOL!
Here are some tracks made by folks who pass files over the net. My name is on a few, but Key to the Highway is mostly me. :-)
