3 months post mirena, and scared might have ALS.

Ok I been reading a lot of mirena symptoms here, and like to hear if any of you ever thought of having MS or ALS. Im 3 months post mirena and some days i feel better but then the ugly days come and feel like i have a disease that Drs cant find, and that i will die. i will post some of my symptoms to see if any of you may relate to this also.
panic attacks (no so bad any more)
muscle twitching
weakness
problem thinking or consentrating
shakiness
shooting pains throughout body
nausea
anxiety
blurry vision (got better)
weight lost (provably do to lost of appetite)?
feeling of fear
gagging feeling come and goes.
this are some of my worst symptoms and i dont know what to think im thinking of start taking Zoloft because I can't take this any more. some of you here said that got better in 6,9 or even 12 and 18 months and i really don't think i can make it through just with natural supplements, I been eating healthy and taking L-teanine for anxiety but dont help much. If u are one of the ones that are doing better please share with me your story. Tank you and GOD Bless..
