It might be worth a shot, but I also have to express a reservation. It might be you don't have the resilience to put up with the kind of challenges this work could involve, day after day. For whatever reason, you have not held a job in quite a while (unless I missed something). As you expressed in your resume, you probably need a bit of shielding from pressures, yourself. It wouldn't hurt to interview and ask a lot of questions, and maybe suggest you would like to start on a trial basis with no expectations on either side.
