Are you unsure about when to use
sentirse and when to use sentir?
Both verbs mean 'to feel':
Use 'SENTIRSE' if you are saying 'HOW' you feel?
(use sentirse with adjectives and adverbs)
No me siento bien. I don't feel well.
Me siento alegre. I feel happy.
Use 'SENTIR' if you are saying 'WHAT' you feel?
(use 'sentir' with nouns)
Siento mucho dolor en el estómago. I feel a lot of pain in my stomach.
No siento alegría. I don't feel happiness.
Sentía hambre. I felt hungry.
Tip to remember:
Rhyme 'what with not'.
How you feel 'is' reflexive (sentirSE)
What is not. (sentir)
