Dear Theresa,
It is good to read lam-rim books, not heavy philosophy, and not just any Dharma book, but lam-rim books, commentaries on guru yoga, Liberation in the Palm of Your Hand, etc. These leave positive imprints on your mind. Read Dharma books, think about them, and let your mind reflect on them, so they leave positive imprints.

Don’t think only of yourself and your problems. If you are thinking this way, then you need to read more Dharma books and also do more practice, chant mantras, etc. Don’t think “I am the cause of all the problems” or even that your problems are so big. Instead, do Chenrezig practice, chant mantras, do guru yoga practice, keep reciting mantras, do purification practices, and read lam-rim books, not many other Dharma books, and not just any books, but good, valid Dharma books. Keep reading and keep doing your practice.

Don’t only think of your problems or that your problems are the cause. That just makes it worse and worse, so don’t think that way. Change the object of your mind.

Keep doing mantra recitation of OM MANI PADME HUM. Try to do one or two million recitations or more, with bodhicitta meditation.

Also, do Lama Tsongkhapa Guru Yoga with meditation and read valid Dharma books.

Keep your mind in peace, then you will have less problems. Life is short, so keep your mind peaceful and make your life meaningful, then people around you will also have more peace. If you are happy then other people will be happy. Try like this.
