I think i have mild dyslexia?

ok so i think i am midly dyslexic. i've read on symtoms and found that i have some but not all. it takes me a really long time to copy notes off the board and i look at it every one or two words. i sometimes get words mixed up by having a letter one place before or after where it's supposed to go. i always have to recite the alphabet in order to figure out which letter comes before or after the one i need. i sometimes have to hold up my fingers in L-shapes to double check which way is left and which is right. if im inthe car with someone giving directions ill normally point and say "this way". i can't read out loud very well and i don't really like to. when i'm texting i rarely used punctuation or capatilize letters. when something is in small print it is very difficult for me to read, even with my glasses. the other day in marine science we had to read an article and i kept jumbling up the letters in the words and had to look at it a few times. i can normally spell correctly, when im typing ill sometimes have to use a backspace because i put a letter in the wrong place but i dont really think that has something to do with it. when i have to read a passage and answer questions i'm constantly looking back at the passage or i just get impatient and guess. i love to write though. my feelings are best expressed when i write, and it's how i explain a lot of things. i'm very good at geometry but not so good at algebra. i hate showing work. i can be really disorganized and my room never stays clean. i cant be told multiple things at once, i have to take things step by step because i usually forget what to do. my parents will tell me to do something if im home by myself and watching tv and they come home and tell me i didnt do it. i'm not sure if i have dyslexia but i think i might have a mild case. sorry for the long details but i would really like to get some opinions from people who know what they're talking about. thank you so much :)
