Well, that´s what happen when you take drugs. You won´t be happy all the time.
To pursue this 'happiness' one ends up redoing it many times and addiction takes place.
This triangle you said will be your life and you will take with you all of you dear ones.
Any reasonable advice from anyone I suppose would for you to stop doing that specially because you don´t seem to know the consequences, or are not very familiar with the routine. Believe me, they can be very harsh.
The problem with this advice, regardless of this making sense or not, is that the person continues using it right?
Nothing glorious about being a junkie. It´s a very sad and limited life.
So I would advise you not to continue using whatever it is that you are using.
All the best man!
