How can i file by mail if i dont have my w-2's and i cant request them from the irs because i cant make an account with them?

If you need a copy of your W-2 then ask your employer.

You can get a free "Wage and Income" transcript form the IRS but that is is not a copy of the W-2 and contains no state information.

You can get an exact copy of the W-2 from the Social Security Administration for $81 per copy.

You have to request the W-2s from the companies that you worked for.
