Big hugs to you, Pikachu. You are stronger than you know.
I am a big fan of meditation for unraveling and healing painful memories. Transcendental. Ishaya's Ascension. Zen Buddhism. Silent prayer. There are some very powerful, highly beneficial forms of meditation out there.
Just as brushing our teeth 2 or 3 times a day leads to healthy teeth and fresh breath, so it happens that 15 or 20 minutes of quiet meditation 2 or 3 times a day leads to healthy emotions and a fresh outlook on the past, the present and the future.
First and foremost, be kind to yourself. You deserve it.
