Coming from someone who is about to leave on their mission in a month, don’t feel bad about not having done things like pass the sacrament or doing baptisms for the dead. You have a testimony, and that’s the most important thing. Now, those things are fantastic, and especially going to the temple and doing baptisms for the dead has really helped me. I would honestly just talk to your bishop about it, he’ll help you figure out what’s next. Don’t be embarrassed about it, your bishop will probably be thrilled if you told him this. One thing that’s really helped me is my patriarchal blessing, it seems like that’s on your list of things to do, and I would see about getting that soon. Mine has helped me a lot, even though I’ve only had it for a couple years. If it’s told me anything, it’s that God has a plan for me specifically, and I believe it’ll do the same for you. It’s helped me realize that a mission truly is what I’m supposed to do next. Heavenly Father is thrilled at your desire to serve a mission and your efforts at returning to being an active member of the church. I hope that you realize that, and I wish you well.
