Well it is partly CBT. CBT is, at least the cognitive part, about looking at things logically, based on evidence, and challenging your feelings accordingly. So you say his answer is usually that either don't worry about things or focus on something positive. That does fit in with the CBT way of looking at things: What are the chances of X happening? Low? So don't worry about it (at least don't be so afraid). So if somebody threatens you, and you can't sleep cause you are deadly afraid of being killed, the chances of that are very low (assuming that same person has not done something to you before or anybody else and that all we are dealing with is just a person upset and making a mindless threat).

However, there are is more to therapy than that and it seems you don't feel heard or cared for or taken seriously. CBT works well within a caring relationship. It is very easy to feel ignored if the person is using logic and evidence not as a way to help you deal with emotions that are there for no "good" reason (feeling fear in face of a lion moving towards you will make you run for your life, which is good, but facing that same exact fear in face of an angry cashier is gonna be a problem) but as a way to trivialize your worries and your pain. When you feel something it is very real. A good therapist is able to work through that with you, and any solution, be it CBT related or not, if pushed on you (like to say think positively about graduation) can feel out of place and frankly, just dumb. Try to sort out if you and your therapist can get on the same page of if it's time for a change. Good luck.
