If you overstayed your last entry as a visitor by 7+ years, you likely have a serious unlawful presence issue. If you depart the U.S., you may trigger a 10 year ban to returning.
In addition, even w/o the unlawful presence issue, you would not likely be able to obtain a new B-1/B-2 visitor visa after overstaying your prior visit by such a long time.
You are not in a good position as you are currently here w/o status and if discovered could be put into removal proceedings. If you depart the U.S., you will likely trigger a 10 year ban to coming back because of your unlawful presence.
You should strongly consider consulting with an immigration attorney to discuss your situation. You are in a tough situation and you may want to review everything with an attorney.
