Getting rid of a HUGE pimple problem? 15/m?

Hello
I, please ask you to read the WHOLE post before you answer.

First of all, I am a 15 year old male, and I have had a HUUUUGEEE pimple problem ever since I was around 13, and it's getting worse BY THE DAY
Okay, so I HAVE read all these "home remedies" to cure acne. I have tried most of them, some including toothpaste and baking soda with lemon juice.
I can tell you now, that these have absolutely NO EFFECT on me.

Secondly, my parents have had past experiences with acne. My mother's response to this was simply not to touch the pimples/face, and they will go away. My father's response was to wash my face three times a day with oatmeal soap.

I HAVE DONE ALL OF THEM!

Now, you may be saying that it's normal to have acne etc etc, I know. I'm not asking for an "on the spot" permanent cure to my acne, I want tips on how to gradually decrease the acne, that's something I haven't gotten out of my parents as yet. Whenever I ask them to take me to a dermatologist or any skin specialist, they refuse to, because they say the two home remedies are more than enough.

Previously, I was sick, and my parents took me to the doctor. The doctor *NOT A SKIN SPECIALIST* noticed that I had a terrible amount of acne, and he prescribed "Akamin" tablets. They actually made it worse.

Lastly, I am drinking about 7-8+ glasses of water daily, however, I am not exercising, yes, i know, it's something I need to do, and i will.

If you could suggest anything helpful for me, I would greatly appreciate it.

Thanks.
