Semele's experience is much like mine, I'd asked for a PD consultant referral from my GP, 6 months before official confirmation. I found that having an answer to why I was feeling so bad helped me concentrate on how to get the best out of each day. Timing of meds and being able to alter the daily schedule help me a lot.
PD is not in itself life threatening so get on and do those things you always wanted to do, within reason. I joined a golf club and play twice a week, not always well, but I find exercise that I enjoy is key to keeping my spirits up.
Do insist on being given a full choice of the various medications available. There are pros and cons with nearly all of them and what you get offered seems to vary depending on the local PD team's experience/NHS directions.
I think it is essential your family and close friends know about your condition and meds, including the possible side effects. Their feedback on how you have or haven't changed could save your relationship or life savings. PD meds can make you think your actions are perfectly reasonable, when in essence they are not to those who care about you. What are you like without your inhibitions (i.e. tipsy/drunk)? This can be an indicator of what some of the drugs could bring out into your daily life.
Even without the meds, you may get the feeling that you're going to do something now before you're unable to do it. That's natural in my opinion as faced with a life changing condition, changes to your lifestyle are required. Bucket lists are common, just remember we've probably got a lot longer to complete the list than those given a life threatening diagnosis.
I've found that PD is very selfish and my ulcerative colitis has virtually gone away as PD 'wants' full control. I've even stopped getting horrendous hayfever since I was diagnosed at age 44.
I'm 53 now, and can still do everything I could do at 44, although slower (way too slow for my job), but then that's one of the joys of ageing.
On the job issue, I was prepared financially and my employer / consultant have been fantastic. There's lots to read about on the forum concerning work and benefits.
The sunrise and birds waking is something I now see and hear more often, so I'm off now, I can have a nap later.
