If you are in the US there is a website called womenslaw.org that can help you find low cost or free legal assistance in your state. It's been a helpful resource for several people I know in a local single parent support group.

Every state has different specifics regarding divorce and this website came help answer questions based on where you live like factors that determine alimony, child support, marital assets, etc.

I wish you the best and hope you find the happiness you deserve. And you do deserve to be happy.
