I'm going to copy paste what Plenus Venter said, because he said it so well --
Welcome to the Faith. Deo gratias!
I agree, attend the SSPX, but stay aware of the issues.
The SSPX is surely infiltrated, just as Pope Pius X warned us in Pascendi that the enemy is now within.
The Society made a U turn back in 2012 down a road that, ever since 1988, it had warned was the road to death, to the loss of our faith: that is, an agreement with modernist Rome without first agreeing on doctrine.
Ever since, they have changed their attitude towards the Conciliar Church, identifying it simply with the Catholic Church, and they have drastically reduced their criticism of the errors and scandals.
They are increasingly friendly towards Ecclesia Dei type communities who accept the Council and the Novus Ordo and who have doubtful Orders.
They increasingly allow priests from the Conciliar Church with doubtful Orders to work with them without receiving conditional ordination.
However, there are still many solid priests who give good doctrine and valid sacraments.
Just beware, and stay in touch with the Resistance so you know what is going on.
And I think you should get your Baptism and definitely your Confirmation checked by a good Trad priest. You will definitely need conditional Confirmation.
I would add --
Make sure you support the Resistance as much as you can. There might be zero in your area -- for now. But on principle, you should support any priests' efforts to establish independent chapels outside the SSPX structure. You need to think ahead to the day when a newly-formed SSPX priest shows up at your SSPX chapel. And that WILL happen. The Old Guard won't live forever, nor will they necessarily be able to offer Mass until the day they pass into the next world.
The new priests are NOT formed the same way as the old. Their attitude and beliefs re: the Conciliar Church are the same as the FSSP, if not more liberal. They are NOT the same as the position/beliefs of Archbishop Lefebvre whose apostolate (SSPX) was so highly blessed by God. Validity of your priest is important, but it is NOT THE ONLY IMPORTANT THING.
Think about it: immediately after Vatican II, ALL THE PRIESTS WERE VALID. And yet, how many of them breathed out Modernism and acceptance of the Modern World, and other abominations, as a dragon breathing fire? Who implemented the destruction of the Faith in millions of souls? VALID PRIESTS.
