That depends on context. Can you provide one?
Somebody helps me OR somebody Help me ?
which one is correct ?
"When I have too much work for one person, somebody helps me."
Note that this is the Simple Present tense. If someone is helping you now, you say, "Someone is helping me" (Present progressive), not the simple present.
Now that you realise the importance of context, you should be able to supply some next time.
You are new here, so I will explain a few things to you.
1. Use capital letters.
2. Don't use words like "wanna" or "gonna" here.
3. Don'e leave a space before a punctuation mark. Do leave one after (as you have done).
4. Don't use abbreviations like "sb" or "sth" - they don't mean anything to some of us.
5. Join two sentences with period (or a semi-colon, or sometimes a dash), not a comma.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
