The flying alone thing. While I have to admit I did it too when I was at your stage of the game, it can be very dangerous! I haven't done it since. Your Instructor specificly told you not to come back out & try to fly for 2 reasons IMO 1) Because he didn't feel you were ready to land, much less solo or he would have had you doing landing approaches & then landings & touch & goes, Which he will probably get to soon if he takes you back as a student. 2) If you were to catch a prop cut in the wrong place like severing an artery & you're all alone out there, you could bleed out before anyone got there to help you! I know that sounds rather extreme but it is very possible. Just something to think about. Nobody wants to see ya get hurt here or discourage you in the hobby.
Just think about what happened as well as what has been said here and I'm sure you'll realize that everyone, including your instructor just wants to see you succeed safely!

As agexpert pointed out a no-damage crash into a bush doesn't exactly count as a successful landing, you got lucky.

Finding RCU about a year ago was a very humbling experience for me too. I was trying to fly planes on my own that were way over my head & I was killing them as fast as I could line them up![:@] After finding RCU I took 3 giant steps backwards got Trainer planes & while it may not have happened as fast as I would have liked, it did happen for me. I am soloed & signed off by the head Instructor of our club & now being told that I'm ready for that #2 plane. So hang in there & see if he won't take you back. You'll be flying on your own before you know it, hopefully with a flying buddy though not alone, bad things can happen when you are out there all alone. Good luck.
