It may be a good idea, and may not. As you said... it could kick up your anxiety, which may end up in a relapse. If you can find a low-stress job then I wouldn't see no problem with it.
If you end up finding / thinking you can not handle a job at this moment... why not pick up a hobby? You could possibly also turn that hobby into a little money, depending on what you like to do.
I started vegetable gardening some, which if done at the right time... I can buy a bunch of seeds, start them off, and then put an ad online / in the paper selling the small started plants to people who have problems / not wanting to start from seed.
