If a person falls into a bit of workaholic super focused withdrawling from golf fishing etc can anxiety or panic attack happen ?

Yes: I have found that addiction (workaholic, golf, etc.) comesout of a belief that "i can't function without ....". Removing that prop will often result in a sense of loss, and anxiety untill confidence is developed. Therapy helps.

Not enough info: It may be most helpful to think of anxiety and panic as "fever"-- relatively nonspecific responses to a wide range of possible underlying psychological issues. Being a workaholic doesn't "cause" anxiety, but it may be an indication that you are trying to avoid or distract yourself from something emotionally troubling. Avoiding emotional issues, rather than facing them, is a recipe for trouble.
