I really want to follow the Little Way of St. Therese of Lisieux, but how?

For context I'm 13F and I'm also autistic, which makes me struggle with a lot of things that other people might find easy.

Lately I've been going through harsh times in my life: I feel useless, that I'm a good for nothing, that I deserve to suffer... I'm trying to get out of all of this but it's so hard for me, I haven't gone to church in months and praying feels like torture... The greatest inspiration I'm trying to get is from the life of the Saints, especially St. Thérèse of Lisieux because although she didn't do great things like miracles or having visions she put love in all of the little things she did, and because of this she became Doctor of the Church. I really want to be like her because she teaches us that the little things you do can become great things in the eyes of the Lord and you don't have to be perfect to be a saint.

Because of this I really want to follow her Little Way, but I'm not sure how. How can I put all of my trust in God, if I have so many things to do? How can I put joy in all of the little things, if my autism makes things like going outside without headphones impossible? How can I build a deeper faith in God?

God bless you.
