Greetings @ivrus!
You’ve got some great suggestions here already- adding to what has already been offered, we actually have a Self-Care Tag here in the forum. If you click the link, all topics discussing Self-Love/Self-Care work will be available for you to browse through 
I would also suggest looking into getting a Rose Quartz Crystal- they are very popular, pretty inexpensive as far as crystals go, and I’ve found it’s a stone that helps both with nurturing self-love as well as raising one’s confidence and comfort levels 
Whatever you choose, I hope you’re able to find some lovely ways to work on self-love and confidence!
Blessed be!
