I really feel you on this, the last few weeks of pregnancy are so tough and not being able to sleep properly makes everything feel so much harder. When I was at that stage, I found that using a body pillow to support my belly and knees made a real difference for getting comfortable enough to rest. You can also try doing some light stretching before bed or taking a warm shower to help your body wind down lah. Hang in there, you are so close to meeting your little one.
