Help - preganncy nausea

I’m really struggling, my pregnancy nausea has been horrific, it’s there all the time and never leaves. I’m also experiencing feeling weak often and with a toddler that’s just not manageable.

I have anti sickness medication which hasn’t helped at all. I feel I have tried everything and now I’m suffering mentally. I struggle to get out of bed, I can’t go out, I can’t live my normal life and my heart is broken at how low I feel at a time where I should be happy and grateful. I feel so selfish for feeling this way but I’m not sure how to go on anymore, it’s really really killing me 😞
