Since my I-94 has expired and my I-130 is pending, am I on a wrong stand and what other options do I have?

You are now out of status and accruing unlawful presence. Unfortunately, once you are unlawfully present for 180 days, if you depart the US, you will be barred from reentry for 3 years; if you are unlawfully present for 1 years, if you depart, you will be barred for 10 years from reentering. The fact that your mother petitioned for you through the I-130 is good but even when the priority date becomes current for that application and you would be eligible for a green card, you will not be able to get it because you are in the US unlawfully. Your only recourse for legalizing your status within the US once you are unlawfully present is through a bona fide marriage to a US citizen. Please let me know if you have any additional questions or how I can be of further assistance to you in this matter.

If you are a minor child and you're mom is a USA citizen, that isn't exactly the correct thing to do, but it's a start. If you are 21 or over or if she is not a USA citizen, then generally speaking, you are now considered illegally here.

You should have applied for an extension of your B2 visa before the I-94 expiration date. The filing of an I-130 by your mother will not give you legal status. You should consult an immigration attorney.

Once the date of your I-94 period expired, you fell out of status. If you were over 21 years when your mother filed your I-130, your petition is in the F2B category, [unmarried adult child over 21 of an LPR]. A visa in that category will not become current for about 8 years. By way of comparison, a visa in that category which is now current was filed Nov 2005. If your mother becomes a US citizen, the petition is then reclassified into F-1 [unmarried adult daughter of a US citizen] Your reclassified reduces your wait time by only a few months. Note that filing a petition gives you no right to remain in the country nor does your unfortunate medical situation.

Since your I-94 has expired (i.e., your B2 status has expired), you are out of status, even if your initial visa hasn't expired (the visa is only for applying for entry into the U.S., it's the stay in the U.S. on your I-94 that determines your status in the U.S.). You mentioned that your Permanent Resident mother has filed an I-130 petition for you, In your question, you didn't mention your age, which is important, because it would determine under which preference category your petition falls . Also, you didn't mention which country you are from, because the priority date in each preference category depends on which country you are from. All of this is only important if for example, you are under 21 and your mother has a way to become a U.S. citizen, so that you could become an "immediate relative" under immigration law. For a person who is *not *an immediate relative (e.g., son or daughter of a permanent resident over 21 years of age), to file an application for adjustment of status ("Greencard"), that person must be in status, and must not have been out of status at any point of their stay in the U.S. For immediate relatives (that is spouse, child under 21 years of age, or a parent, of a U.S. citizen), there is an exception to this rule. That is, a person who is an immediate relative, that person can file for adjustment of status even if they are out status. So in your case, it's important to determine if you can qualify as an immediate relative, otherwise you would not be eligible to file an application for adjustment of status.
