I need some support for starting a new job?

I start a new job this next week and I am extremely anxious about it. I am bipolar and have not had good luck with jobs and I want this one to work. I do not want my anxiety to take over and screw it up. I am on medication, well actually my doctor just changed my medication from lamictal to neurontin. I do not know if the neurontin is working as well as the lamictal. The other problem is that this new job is somthing that I have not done in many years. It is a maintenance mechanics job at a distribution center for a large grocery store chain working on their trucks. I did this type work many years ago and I am scared I have forgotten a lot. will it come back to me. I dont know I guess the whole thing just scares me. This question probably does not make a bit of sense

Dude, Nobody knows the job they have to do when they first start because each job has its own expectations. Just try as hard as you can and find ways to go that extra mile and your efforts will be rewarded. Take all that inward though and turn it outward. Do not dwell on your shortcomings (everybody has them) dwell on your strengths and how you can inprove them.
