ETA: Ooops - I corrected this because every time I wrote "yo" it autocorrected to "you" - I hate when that happens! Also I have no accents or tildes anywhere so you'll have to wing it!
It's great that you are trying so hard! I'm looking at your Spanish, and want to give you some basic rules for see vs. ester: Ser (e.g. yo soy) is for usual characteristic (Soy morena, ella es alta), origin (Soy americana) or time (Son las cinco de la tarde). Estar is for location (Estoy en mi casa) or temporary/action (Estoy aprendiendo el espanol).
You always want your articles & adjectives to agree with your noun, so "mis palabras no estan correcta" (my words are not correct) vs. "mi hermana" (my sister). I realize your post auto-correct just as mine has so it's frustrating to keep going back to fix things! I know you wrote "es" but auto-correct changed it to "is", for example! "Es la meyor soy puedo" - you're trying to say "This is the best I can do" but you have 2 conjugated verbes (soy and puedo) and you want to say "lo mejor que puedo hacer".
The other posts are correct about reflexive verbs - it's not completely intuitive. The "-se" ending is for doing something yourself or someone else doing it themselves. So quedarse is for you (or someone else) remaining where they are, vs. a bus waiting at the depot (which it doesn't do on its own) or you leaving the pencil on the table. See the difference? So "callate" (with accent on the first "a" is "shut up" or "quiet yourself" - in the command/imperative form. (And I haven't figured out how to do inverted punctuation, accents or other diacritical marks on here!)
Actually, the most sensible thing might be to ask a teacher friend for a spare textbook (sometimes from a discontinued series when they buy new texts) or to check with a textbook publisher or even a place like Amazon. See if you can buy the teacher's version that has the answers! The lessons are generally organized in a logical fashion so you learn verbs that relate to each other (and conjugate similarly), how to use direct and indirect object pronouns (as you tried to do in "la mayor...", and, yes, reflexive verbs. It's actually easier than learning English in many ways because the Spanish words vary more than the English in many cases! If you use a textbook and actually practice the exercises and THEN check the answers, you will learn a lot. And the books are designed for native English speakers.
I commend you for learning another language - it's such a gift, and it's so important that Americans see themselves as part of the world community and willing to reach out to others. So many of us have attitudes like "English is supreme" and there's a level of arrogance about "Learn English, or else I have no use for you." So keep it up! Don't be afraid to enroll in an adult ed class - you will get to practice with others, and that's invaluable!
