how important is the grammer in the turkish language?do you need to know alot about the grammer so you can know the language? or is it just best to know the grammer, i am having a bit of trouble on the grammer and feel like giving up on it but i know i shouldn't i just want to know how important it actually is

The most important thing is suffixes maybe Also suffixes depend on the vowels, pronounciation. Every learner needs to know both to handle with Turkish

Here is my advice:

Study grammar only when you come across to a grammar issue in a non-grammatical context e.g. a story, any text, a speech, a song.

Example:
Let's say you are hearing or using the phrase "teşekkür ederim" frequently and you wonder how it is constructed. Because you are curious about a certain phrase it will help motivating you to learn the grammar related to it and you will remember it easier.

If you are not curious to know how "teşekkür ederim" is constructed then don't study its grammar.

The phrase looks very simple, isn't it? Actually it isn't. There are some grammattical issues involved, like the verb "etmek" and the -im personal suffix at the end.

The verb "etmek" is an auxiliary verb. It is used mainy with foreign origin word to make verbs out of nouns. For instance "teşekkür" is a noun (thank) and "teşekkür etmek" is the verb version. Smillarly 'dans' in Turkish is a noun (dance) and "dans etmek" (to dance) is the verb version. We have also "yardım etmek" (to help), "şikayet etmek" (to complain) and many more these kind verbs.

Let's have a closer looks on "ederim" :

et + er +im :

et: verb stem of the infinitive etmek (-mek is infinitive suffix and by dropping it we simple have the verb stem). et became ed according consonant mutation rules.

er: Simple present tense suffix.
There are too many details on this tense. They are best explained here:

You might wonder why you use -er and not -ar here. So you need to learn vowel harmony as well.

-im:
This is a type one personal suffix for first person singular.

As you will see on that link type one personal suffixes are used for Present Continuous tense(-iyor), Simple Present Tense (-er), Future Tense (-ecek) and Infenetial Past Tense (-miş.

There are other types of personal suffixes and there are possessive suffixes that are also different for each person but you don't need them now as they are unrelated.

Actually type one first person singular personal suffix has four forms:
-ım, -im, -um, -üm
Again you choose the correct one (-im in this case) according vowel harmony and the last vowel before you add the suffix.

Please feel free to ask any questions about this grammar intruduction.

Well, of course you don't need to study so much grammar only for "teşekkür ederim". It would be perfecty alright if you had studied only one topic, for instance the -im suffix and why it is -im. Anyway, I hope I could give an idea on how to study grammar.

One more hint:
When you are reading a text, or listening to a speech, if you understand half of the sentences when checking the dictionary then never study any grammar and keep reading more advanced texts until you don't understand more than half of the sentences.
