It is obvious that you are a hard working employee which any company would be happy to have in their work environment. Difficult I am sure when having to leave a bad work environment as it sounds like none of this was any of your fault.
Glad to hear that you have talked to a job counselor who can help in working with your resume and create one that will stand out when sending it in to a potential employer. Some suggestions I can offer to you at this time to help locate future employment that can make you happy and offer growth as well.
1. Start by working with a temporary employment agency as they can help with resume writing, building upon job skills, as well as placing you in positions that are temporary at first but can grow into full-time. Look at agencies in your area as well as some of the bigger firms such as AppleOne and Kelly.
2. There are legitimate home based jobs that would allow you to work in the comfort of your home as the physical problems you experience would deter from working in a office based environment. I have received this question often from other customers who ask about legitimate home based jobs as I have given out info from consumer advocate Clark Howard who can be found on CNN:
3. While going back to school may not be something you would want to consider, possibly taking though a class via your local community college and/or adult school that can offer some updating on your skills so that you can place these learned features on your resume.
4. Check also with a book that I highly recommend that can help guide you in future career decisions. It is called "What Color is Your Parachute" and has been the standard for career choices for decades. You can find the latest copy at your local public library.
Stay positive in your search as I believe with some of these tips I have offered above can help guide you to a new and positive outcome for a new job.
