Helppp please ‼️

I’m in my second trimester, and pregnant with my 3rd baby . But I’m so tired constantly I just wanna sleep , I can barely keep my eyes open , I cry all the time because my body just doesn’t wanna go at all , I have been leaving work early everyday because I just can’t stay awake and I feel half dead . What can I do to help this or give me some energy ? I was never like this with my other pregnancy 😩😩😩
