Jenny, you don't have ALS.
I've reread your posts and it seems as though because you were right in your diagnosis (via online research) of your dear baby, Lilyrose, that you've done the same thing for yourself.
It is common after the death of someone close to look more closely at your own health. I know when my dear friend died of cancer, I was constantly worried that each little ache and pain was cancer. I may be that you even wanted to die after your baby died. That was a possibility because of the new pregnancy. So an ALS diagnosis would help you die a little at a time.
Please LIVE for the sake of your new baby. I wish I'd paid attention earlier when you said you couldn't take drugs for depression because you were pregnant. I did, and my baby turned out just fine. Many drugs for depression are now okay with pregnancy. Zoloft in particular. Please focus on your baby and it's health. You are not dying. You should be living life to it's fullest.
Most everyone on this board is either suffering from ALS or has a loved one that is. Their symptoms have been identified by an ALS specialist. Those doctors don't just hand out "yes" or "no" lightly. When they say no, it's for real. They have no reason on earth to lie to you. It would go against who they are as doctors. It would be like a doctor knowing you have brain cancer and telling you, "no, you don't have brain cancer".
My mother will not be here next Christmas. She probably won't be here for Easter of this year. She would do anything in the world to have a few twitches and some eye floaters. Please, out of respect for those with a positive diagnosis, stop trying to die. You're so young, so much of your life ahead. Seek help from a therapist before your baby is born.
