I'm chiming in late I know...
Your experience with your therepist not calling you back.... Of course she's busy; it's her job to be busy. It's also her job to be there for you and that includes returning your call or having someone on her staff return your call. It was important to you; you have every right to be angry about her lack of professional consideration.
Next visit, ask her how you should handle such a situation in the future. If you call and she thinks it is an issue for your primary doc, then tell her you expect her to convey that to you---you are not supposed to be in a position to have to guess why she isn't returning your call/answering your question. She of all people should know you have to communicate with words, not with guessing. She can easily have a staff person call you and tell you that.
about the job. Hitting the pavement is old-school, although it can work. Better yet these days is registering with an agency. They find jobs in all kinds of areas of work. Check them out in your yellow pages, and go to their web sites. Many times you register on line, then go in and talk to them (take your resume) and they will do any necessary skills testing. Since you are using a computer, you have computer skills, so they will probably have you sit for an online computer skills test so they can know what jobs to send you for. Rarely do agencies charge fees to the applicant; now days they are paid by the companies hiring. Many companies use agencies for all their hiring so they pay the agency instead of having someone in the company to do the interviewing, etc.
You can find full time work or temporary work through an agency. Some people like doing different jobs so they do temporary work and work a while here, a while there... And some agencies even offer benefits after a period of time.
I hope this helps! Best of luck to you!!
