Woke up a few weeks ago and felt like it was difficult to walk, like all limbs were tightening and i was moving slower. it went away i started shaking but i think from fear. had nausea and diarrhea after. could this have been a stroke ?

Not likely. It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Drink more water.
