oh Ryan...You are in fears. For 2.5 years. After a car incident which might more or less endanger your very life and existence (who knows really if rear back strike is so innocent!). Obviously your body decided it WAS DANGEROUS. And feared people always have shaking hands, wobby legs etc. If you suddenly approach to somebody in the darkness and say BOOOOOO! - the poor victim might even had urinary inconsistence due to rapid release of stress hormones, and would be shaking for hours maybe. About the same goes now with you - but for days, not hours, and I hope, without bladder symptomes (do not blame me if you became induced, it could happen easily in your conditions!).go on, boy, why you do not attend free clinic? it is still a month ahead of you for your insurance, would you like to attend the paid doc crawling?Sorry if I am sounding a bit brisk... But I see that you are ruining yourself, and this is a kind of behavioural ruining, very nasty... ALS really substituted in your mind the well prominent list of facts, namely that you:- had physical traumas well associated with onset of twithches - you suffer personal issues, and were used to conseal your sufferings- ALS is very rare- you are far too young for getting it - your symptomes do not match it - you are over 20 month in neurological symptomes wich is also far too long for ALS onset. looks like you do not see anything else but only I AM DOOMED carved everywhere...and you just choose a name of ALS for that doom
You know, having obsessive fears is like having diabetes. Usually person is born alerady with chances to get diabetes (or obsessive fears too - for example HMS people like me have 16 times higher occurences of depression and phobies compared to general population. 16 BLOODY TIMES!!!! - just due to small mistake in some gene responsible for making enough collagene in our bodies!) and after onset it would be diabetic till the death. Same is for fears. Getting their onset means you highly probaly would suffer with GAD or GAD-like condition for the rest of your life. it is a disease too and well ruining. but with diabetes, you might choose either daily insulin shots or any new treatments to control it - or you might choose neglectance, and get obesity, diabetic neuropathies, blindness, heart attack, diabetic foot etc etc.etc. Same is true for obsessive fears.For some unknown for me and probably very personal reasons you seem to choose neglectance of your real condition in favor of percieved one.Think of it please.I know people who choose to stay with fears. it was their personal choice. But... the quality of life with this choice is miserable, really, and so called secondary values that such choice brings into the rest of their lives are so... so... in other words, what I know personally is that when somebody choses to control fears and goes this way, he or she usually starts to recieve the same values (love, attention, sympathy, even money, name whatever makes life good and valuable) as a primary, not as secondary.
Until you a) manage anxiety and b) internalize the idea of its benign however sometimes very boring nature, the program in your own show would be always new and scary for you 
.Do not worry, look for LisaLM. I think she had seen all that shows and knows every trick. You would be OK too.
