I feel like God doesn’t like me… What should I do?
Feelings do not necessarily reflect objective reality. In this case, we know the objective reality that God loves everyone infinitely.

I suggest speaking with a priest and/or spiritual director for more specialized and individualized help. I also suggest the following book, which may be available through your local Catholic bookstore:
Story of a Soul by St. Therese of Lisieux
