Advice: struggle is real

Hi, i am new here and i have a question. I come from the theravadda tradition. Without getting into the details of my life everyday is a struggle. Im hated by many because of my past wrong actions and simple things such as sleep and making money are difficult. What wisdom can Buddhism give me to not allow the pressures of the world to get to me?

I would like to work on my speech. I struggle with cussing and other vitriol such as snapping on people.

Thank you for your help. May you be happy and at peace.
