Yes, it does include a freedom "from" religion clause. If you take the time to learn anything about the framers of the Constitution, you'll know that they were dead-set against allowing anything invoking divine authority to creep into the system of law and government which they were creating. Not all of them, but most, and that wisdom, thankfully, carried the day.
What language exactly are you writing in? It appears to be english but you appear to not understand english. I quote the first amendment.

Where in that set of phrases do you see a freedom "from" religion? It enshrines the principle that the "government" can neither establish a state church or prevent the free exercise of any religion. It does nothing to protect atheists from having to live around non-atheists. You have to make that choice yourself and move elsewhere if you don't like your neighbours. It binds the government to prevent them from interfering and it does not grant you any rights as a citizen to lord over others who choose to practice a religion.
