Me name is XaNax

"My name is XaNax"

If you were going for a "talk like a pirate" joke, then it would be something like "Ahoy! Me name be XaNax."

I've been learning

Not a mistake per se, but you probably meant to say "I've been studying."
The difference is subtle, but if you want to emphasize the active effort, "studying" would work better in this context.

learning english

"learning English"

The specific names of languages are proper nouns, so they are always capitalized.

for decades

Unless you were going for a comedic effect, you probably don't want to use phrases like "for decades" right after specifying that you are only 34 years old. It sounds a bit pretentious.

Also

"Also,"

It always needs a comma when attached to an otherwise complete sentence like this.

i

"I"

for kids and

"for kids, and"

These are two independent clauses, so you need a comma here. Note that there are exceptions to this rule.

If you not

"If you are not"

interesting

"interested"

Unless you want to insult the reader, of course.

ingore

"ignore"
