Hi, "sentirse" is a reflexive irregular verb, so you'll need a reflexive pronoun to conjugate it. The use of the pronoun is mandatory, regardless of whether it is a regular or irregular verb. "How do you feel?" would be "¿Cómo te sientes tú?" (informal you) or "¿Cómo se siente usted?" (formal you). With a regular reflexive verb the structure would be the same. If you wanted to ask "At what time do you get up?" you'd need to use "levantarse", the regular reflexive verb for "to get up". So you'd need the same reflexive pronoun: "¿A qué hora te levantas tú?" (informal you) or "¿A qué hora se levanta usted?" (formal you).
In these examples, the reflexive verb is conjugated, so the pronoun is placed before it. Pronouns can only be attached to a reflexive verb when the verb is in its infinitive form, as in "¿Quieres sentirte mejor?" (Do you want to feel better?). In this case, there are two verbs: "quieres", which is conjugated, and "sentirte", which is in the infinitive with the pronoun attached to it. You could also say "¿Te quieres sentir mejor?", placing the pronoun before the conjugated verb. This structure also works with object pronouns, so as OCeanDriveVibe explained, you could say "Te quiero ver" or "Quiero verte", both are correct.
I hope this is a bit clearer now, but you might want to review session 15, level 4, where Sonia explains the use of reflexive pronouns when there are two verbs. This is quite tricky, so it's perfectly normal you have questions about these structures.
