car accident

About 6 months ago I was invovled in a car accident. A lady driving too fast for weather conditions totaled my truck with her car and was cited on scene. My jaw was slightly disaligned for which I now wear a retainer at night, whiplash and right arm trauma (used it to block the airbag). What I thought was going to be a quick recovery turned into a nightmare. After months of Phy. therapy, chiropractic care and medical test I was finally diagnosed with RSD (chronic pain syndrome) in my right arm. It is still very swollen and slightly discolored and they say this is all the better it will get and may actually worsen in time. Tomorrow I go to the pain clinic to find ways to manage the pain. This coluldn't happened at a worse time since my husband and I was building a home and both HAD to be working. Now I am buries in finacial woes and get depressed thinking that it is really going to be never ending since my earning capacity is knocked to nothing. My right arm is my dominant one and my job requires a lot of lifting and physical ability (when and if I ever can do it again). I was released to light duty before being diagnosed with the RSD but my job was done for the year . I usually spend every winter working part time at a clothing store, then in the spring return to the greenhouse. Does anyone have any idea how long a claim like this will take to settle? I hear when your done doctoring but in my case that will never be. What is a amount that I can expect from this claim? I really need to shed some light down this dark hole.
