Call me harsh, but get over yourself. Stop blaming everyone else. Can you seriously look yourself in the mirror and honestly say that your menahel was wrong for chucking you and that people like him cause society’s problems? You admit that you were doing things clearly against Yeshiva rules. See that word, rules? It means…that if you don;t follow them…there are consequences. There are reasons for those rules. People who break them stand to be a severe negative influence on their peers. Tell us, were you suspended? Were you given mussar? Were you disciplined? Ever?! IF yes, then you knew that what you were doing was wrong and would result in your expulsion. So stop blaming everyone. The fault belongs to none but yourself.
That being said, you obviously don’t like where you are right now in life, and that’s a good start. As long as you have a desire to improve, there is potential. There are places for people who have had problems with yeshivos. The yeshiva that chucked you is in no way obligated to take you back, or even arrange for your transfer. They can’t take charge of your improvement, you can. Only you can pull yourself out of your current pit. Relying on others every time life throws you a challenge will get you nowhere. Take charge of your own future, and make yourself into what you want yourself to be.
Find a Rav. Find a yeshiva. Find a counselor to help you through any problems that you may be having with family, etc. Find a group of suitable friends. Find a kiruv program if that;s what you need. But most importantly, be aware of who you are and where you are. You need to understand what your current level is if you want to improve. It may be tough, but you really do need to do a cheshbon hanefesh of sorts. Take stock of where you are and where you want to be. Then work toward your future.
