Overwhelming thoughts - Mindfulness and awareness

So I have read and know something about awareness and doing regular tasks with attention and focus. But recently there has been chaos with my job and cause for consternation. Thoughts keep arising from my mind and there has been anxiety and that is overwhelming. I don't really resist them as they are thoughts and as such I know that is the nature of the mind. I try to accept it. But I then feel weak and give way to appease those thoughts and then start acting or reacting to them. Could somebody's experience with Buddhism and meditation here help out with the nature of those overwhelming thoughts? It is possible there is no other way apart from meditation and accepting them calmly. But it gets too strong and then "resisting" becomes a natural tendency and I lose composure. Also the problems tend to keep repeating themselves from my mind because they are long standing problems albeit impermanent. Makes me feel that that is the nature of problems of this worldly life anyway and then I even feel caged.
