Amebix,
Speed is a real nasty drug for anyone who has social phobia or deals with anxiety, as it pot. Because they really make us more paranoid about our world. I've done a lot of both. Kick it to the curb now or a heart attack both real or imagined awaits you.
Our bodies are quite fragile but will recover far quicker than our mind will.
The effects of your anxiety will lessen if you stop taking any more drugs but if you continue, you risk letting your mind run even more out of control causing you to become agitated, confused, paranoid uncontrollably. This isnt very pleasant.
You may have experienced a release of massive stress, whereas before it wasnt too bad, this could be due to many things going on in your life, but it has definitely made your anxiety worse. What seemed alright and quite pleasurable initially has now errupted in your mind and has strengthened the power of this anxious mind.
The mind of anxiety needs to be pacified, not strengthened. I can truly say that stopping the drugs and being of more stable mind is the best drug of all. You can have control over your anxiety, but you must want to.
And wanting to have control over your anxiety means wanting control over your mind.
I hope all works out. Take care.
Jack
