Divorce is not a sin. (I know others have said it, but I want to reiterate it!) Remarriage without a finding of annulment is a sin. You aren’t remarried. You just need to get your bottom back in the pew!!
This is all you have to do to be back in full communion with the church:
Go to confession if it has been more than a year, or if you have committed any mortal sins. (Divorce doesn’t count–that’s not a sin.)
If you have standing for one, you may start the process of an annulment if you wish. It is up to you.
Don’t date unless and until the annulment is finalized.
Really, that’s it! The confession part has nothing to do with your divorce, but is equally binding on us all. The only responsibility you have is to not date or remarry without a finding of annulment of your first marriage. Just get back to church and get active again! There is nothing stopping you! (Given your moniker, I suggest you take those kiddos along, too. They’ve been outside the church for several years. If any need baptism, you can talk to the priest about it. You can also get them in Religious Ed classes, scouting, etc, and depending on their ages RCIC, RCIA, or prep classes for the sacraments. Don’t let this sound overwhelming–these are all options open to you and not requirements. You have the fullness of faith at your fingertips and all you need to do is go!)
Welcome home!!
