Need motivation😴

Is there anything I can do to feel better? I’ve not long found out I’m pregnant again and I have a 2 year old.. but not long after I found out I was pregnant I’ve literally lost motivation to do anything, and it’s starting to get me down.. I constantly feel sick and keep having to stop when I do daily things eg. Putting clothes away or even getting myself ready... I’m constantly so tired and can’t wait to get back to bed when I wake up. I don’t remember feeling this way with my first pregnancy so don’t know what I can do.. is there anything I can take that will give me abit energy or even stop me from feeling sick? I know it’s a part of being pregnant as I had morning sickness with my first but I wasn’t this tired and drained all the time and was able to do my usual day to day things.. makes me feel like I’m failing and I can’t fail, my child needs me😩😴
