You list your religion as Catholic. Assuming you were raised in the Catholic faith then you were given a valid baptism in the Catholic Church. So you cannot receive baptism again, ever. As Puzzleannie stated, there is only one baptism in Christ. If you strayed from God since your baptism (which all of us sinful humans do) then you need to go to Confession.
Do not worry if it has been many years since your last Confession. Just sit down, compare your life with what the Ten Commandments and the Beatitudes say and see where you’ve fallen short. Then go to your priest (or if you do not have a priest yet, go to one of your local Catholic parishes and go to the priest of that church) and make confession. There will be regular weekly times to do this and it is totally private (usually there is a screen between you and the priest so that neither of you can see the other’s face). Simply let the priest know at the beginning of your confession what your situation is (as far as how long it’s been since your last confession, or if you’ve never confessed before) and he will graciously walk you through it so that you can be assured you have made a good confession and receive the Lord’s forgiveness.
