This advice isn't for everyone, but personally my study of philosophy has led to adopting nihilism which has, surprisingly, reduced my anxiety about concerns like OP's. It is this almost backward reasoning that since life is meaningless, it really isn't this gigantic tragedy even if the earth is destroyed by a giant planetary collision and the human race is destroyed. In the grand scheme of things, I don't matter, the human race doesn't matter, and neither does the earth. I will still do what I can to improve my life and others' lives, but accepting this nihilism has allowed me to free myself from the paralyzing anxiety and inaction caused by overvaluing human life. This, in turn, enables me further to make healthy contribution and add what little meaning I actually can to our existence here.
