None but you only can change yourself. Be optimistic my dear friend. think of the people who don't have food for days and hundreds of thousands of people who really don't even have their basic needs to be fulfilled.We are the only remedy for our worries and remind the words in Quran which means 'I will not change you until you change yourself'.Be bold dear friend and tackle the things with thakwa.May Allah shower you peacefulness and security.....Ameen.
