Since how long have you been facing these problems? Do you also feel helpless sometimes? Is the anxiety bearable? How were you as a child? Is there any stressor which has led to your current state? A complete history needs to be taken and only then can some form of therapy and medicines be started. For that you should consult someone online or in person. Until then you can try listening to white noise while you're working and start some form of exercise in the form of yoga or running or zumba.
