14 day suspension

I admit I got super tilted and flew off the rails for this game. I had some crappu games before and got mad so I needed to blow off some steam. It was a D-Bag thing to do, and I deserve my suspension. But I am assuring myself that it was a one time thing and it certainly won't happen again. So after I serve my time and get my account back, is there a chance of me getting perma banned if I don't do something like this again? I love this game and don't want to lose my account, so I won't intentionally feed again. But if I have a bad game and just play like crap or do something experimental and get wrecked and get reported, will I lose my account?
