sending you hugs
You are me 16 weeks ago. Yes its hell on earth and unless you have been there you dont know how bad it is 
You are doing to get dressed (i normally failed) I did well to make it downstairs (in dressing gown)
Couldnt bear OH near me, he had to sleep in spare room.... just him turning over would make me sick.
BUT i got a teeniest tiniest improvement at 14 weeks, (so hopefully you might too), and improved a bit more around 16 weeks, and was alot better than i had been from 18 weeks.
Im now 29 weeks, and am still being sick, and still need my tablets.... but since weeks 18 / 20ish ive started to FEEL better, and im rarely sick more than once a day anymore, so its so much more manageable.
I have also had some consecutive days NOT being sick at all, occasionaly 3 or 4 days in a row 
Having HG is horrendous (and i only ended up in hospital the once).... but i really really hope you start seeing small imorovements quite soon, just like i did.
And yes stay in bed
. I spend 2 months basically only in bed (or ensuite being sick) as moving out of bed was just too much effort
Oh also i had accupuncture from 8 - 18 weeks. It helped SLIGHTLY (giving me a few hours relief) but after a few weeks i got semi permenant needle plasters which helped me too and reduced my sickness a bit as well.
(and when you have HG a few hours of even slight relief IS worth it!)
