hello all.i dont know what i am really doing or where do i make wrong.im into bounties so im using metamask and myetherwallet about a year but im not a pro of them.i was just looking my transections.anyway.
after format my pc i cant reach my account.i feel that i do wrong something very basic but where? when i created metamask and mew account i wrote it seed phrase and private key down.i also noticed somthing 64 digits (it says wallet but i dont know what i ment)
im so confused so i cant explain clearly, im sorry about that.
first i tried to use seed phrase but it says its wrong. (1st and last words are same, is it possible?) my bad maybe. then i tried private key from my notes, i can login but its not my wallet.how can it be possible? thats why im saying i make something wrong very basic.
then i thought it may be the mew seed phrase and i could login with it but it shows something with "HD Derivation Path" "Address to Interact With" and list of address which are what i have no idea.is it the right place to search my account?
can anyone help me with those explaination, i really appreciate that.

i watched videos, read articles but they ddidnt help me.

please suggest me something from start to end what must i do. im not good at those stuffs so be clean please.
thx
