Healing starts with reframing. Instead of thinking, "I was so stupid. I gave them everything and it still didn't work," reframe it as, "I was so in love. I did the best that I could and I REALLY tried. I gave it my all and showed that I cared. It didn't work. At least I tried."
I immediately go silent when something upsets me. it's a coping mechanism i have developed over time. instead of expressing my anger or frustration, i simply withdraw and try to process my emotions in private. i prefer handling my problems on my own
