What do you do to control anxiety after quitting?

I’ve been trying to stop smoking for a while and I’m never able to hold it for a long time. I’m very stress with my studies and I feel like it helps me (I know it’s probably the opposite).

I stopped for six months, but exam time came and I picked up on the habit again. I really want to stop tho, because I did feel god when i stopped, could breath better, food tasted better and all.

But felling anxious really makes me want to smoke. I’m already in therapy but I can’t help it. Is there something you do to take the edge off and do something else besides smoking. I’m going to give this another shot, and any advice would be helpful
