Dear Help Me,
We commend you for seeking help while you are still young and unmarried. The gates of Teshuvah are always open, especially at this time of year. A transcript of the video you mentioned is up on our site
over here. I will try and give you here some advice and useful links to help get you started on your journey to sexual purity and teshuvah.
The first prerequisite to doing Teshuvah is obviously to stop doing the sins. The Chofetz Chaim says that the essence of doing Teshuvah is to make a careful reckoning of what things brought you to sin, or made it possible for you to sin, and from now on to avoid those things like fire. One who does this is fulfilling the Mitzvah of "doing Teshuvah" properly. So sit down now before Rosh hashana and decide what things lead you to do these sins and resolve to stay far away from the "triggers". If it gets hard, you are making progress! The Sefer Taharas Hakodesh, written by the first Shomer Emunim Rebbi Zatza"l mentions, that the biggest tikkun (rectification) of Teshuvah is the the suffering that one feels when the Yetzer Harah comes to him again, but this time he doesn't listen to him!
Chassidus teaches us that a Jew has to look at the past and future as out of their hands, and to see what you did in the past as what G-d wanted to happen. Strange as it may seem, your sins of the past were G-d's will. Only the present is in our hands. In the present, it is in our hands to decide if we want to change, and do Teshuvah on the past. That means that the situation you are in at this present time, is exactly the situation G-d wants you to deal with. Look at it as if you were born at this moment, with all the past memories already engraved in your head. G-d wants you to deal with this situation, and
davka this situation. And this is also a chance for greatness, to be able to serve G-d with joy even though the brain was already influenced by the past. Those who were born with pure minds and never sinned don't have the opportunity for growth that the Ba'al Teshuvah has.
Chaza"l also say that Teshuvah was created even before the world was created, to show us how important it is, and that without it, the world would have no chance to exist. Indeed, Adam, the first man, was shown the power of Teshuvah after he ate from the tree of knowledge, in that he was spared to live for another 970 years. G-d also brought the greatest Tzaddik of all men, David Hamelech, to sin with Bat-Sheva to demonstrate the great power of Teshuvah (See Psalm 52 where Dovid pleads to Hashem to forgive him for this sin), and also to show us that even great men can sin and do Teshuvah.

I strongly advise you to seek proffesional help, as Elya K mentioned. You may want to talk to Elya, he can really help you get started with recovery. See
this page for info on how to call Elya.
I also strongly suggest that you join our
Chizuk list and browse through the hundreds of
tips and
the chizuk e-mails database on our site. If you commit to read a little bit of these things each day, you will start to see real progress.
You have taken the first step, and Hashem will surely help you to purify yourself. Implore Hashem this Rosh Hashana to help you do Teshuvha Be'emes. He hears every true prayer.
