Dangerous advice symptoms and conditions

Oh My Gosh....I cannot believe I just stumbled across this site. Feeling so NOT LIKE MYSELF for quite sometime now made me decide to google Snythroid side effects, wondering if this medication I am on could possibly be the reason I am feeling so badly. I am 50-years old and started taking synthroid (Levythyroxine) about a year ago for hypothyroidism. I have been struggling tremendously with anxiety, mood swings, fatigue, more hot flashes, emotional instability, and sudden weight gain (about 10 lbs) since I started taking it. I never had any weight issues. I have just assumed this was all related to being "menopausal" (and I'm sure some of it is) and stress-related.....but here's the thing....BEFORE I started taking it, I felt "normal" emotionally, I never had a problem with my weight, and never really had any major "pre-menopausal" symptoms....in fact, I think I had A LOT LESS hot flashes and emotional turmoil, BRAIN FOG, etc., BEFORE I went on this stuff. I was technically POST MENOPAUSE two months ago. Okay, so symptoms should be subsiding now. Any menopausal symptoms would/should have been worse during pre-menopause. Again, I never remember having any major symptoms going through "the change" and felt blessed in that respect......so could it be possible that this hell I have been going through COULD be related to this fricken Snythroid????!?!? I want to just stop taking it to see if I feel normal again, but don't know if it's SAFE to go off all of a sudden. What is this Armour?? I cannot believe how many others out there are feeling like me. I hope this is the reason, so I can feel some hope. But now what do I do? I'm sure I still have to get my TSH levels or whatever regulated. Any suggestions out there? I'll try and make a doctor's appt and check levels again and see what my options are...I was told I probably had to stay on this stuff for the rest of my life. Thanks, everyone.
