Masha,
Ha'Shem is real. The "signs" as you refer to them, are all real. Go with your instincts. Your CV and resume will mean nothing soon when the Jews realize that even the United States is their enemy. Soon, every Jew in America is going to pray to Ha'Shem "Just let us leave here and make it back alive to Israel", but then it is going to be too late for all but the fortunate few who can buy their escape. If you have the means and the will, follow your instincts. Miracles are real and they do happen. I can testify to this as a truth. There are a great many ways that a Jew can be important living in the Land of Israel which may have little to do with the life we know here. The whole reason for Return from Exile is to live as a nation again in our own land. Aliyah means spiritual ascension. Living in galut, the world views us as having no G-d - still living under a curse - forced to wander forever, hated, insecure, and in fear. The purpose for our "return" is not that we can have material comfort and the ability to live extravagantly. There is nothing "wrong", per se about living well, but Jews have 'lived so well' for the last 2,000 years in every country but their own, that today the majority of Jews in the world have Returned to the Land of Israel, accepting all the difficulties, problems, and economic disadvantages, rather than endure even one more day as a wealthy successful misfit in a world which doesn't want us to survive. The biggest SIGN MIRACLE of all is the fact that YOU are part of the first two generations of Jews in 2000 years to witness the rebirth of our nation and to be free to return there! Jews worldwide prayed and begged G-d for 2000 years to let them return back to our own Land and Jerusalem, and today YOU can buy a plane ticket using a plastic credit card, arrive there in less than a day, and receive full citizenship just for the asking!
You ask if there really are miracles and signs?
Ask yourself: "WHAT OTHER NATION ON EARTH HAS BEEN HOMELESS AND STATELESS FOR TWO THOUSAND YEARS, PERSECUTED, ENSLAVED, MURDERED, TORTURED, REFUSED TO DISAPPEAR, AND THEN WAS REBORN AS A NATION BACK IN OUR OWN LAND, WITH HEBREW LANGUAGE AND TORAH INTACT, LITERALLY OVERNIGHT?"
Yes, miracles are real, and are everywhere all around us - only most people are unable to "see" them.
There is a spiritual world and because you are seeking it it is revealing itself to you.
Go.
Ascend.
Trust in Ha'Shem and He will guide you the rest of the way.
