Dear @Anobody ,
Thank you for your kind words. 
I’m deeply touched that my advice has resonated with you during this challenging time. It’s clear that you’re going through a lot, and I want you to know that it’s okay to feel overwhelmed. 
Communication can indeed be difficult, especially when emotions are running high. Our brains are wired to shut off our thinking brain when our feeling brain takes over. This response is to protect us and trigger the fight-or-flight survival response. It’s like having a tiger in the room, and our body views emotional distress from our loved ones with the same urgency.
Even I used to struggle to communicate well when emotionally triggered, especially if the emotions were strong or hit sensitive issues. Over time, by practicing self-regulation daily, like brushing my teeth, I have learned to take breaks, regulate myself, and let my thinking brain come back online before continuing the conversation. There is no shame in having louder emotions; it’s your body’s way of trying to protect you. With support and the development of skills, you can learn to control the volume of your emotions.
Writing down your feelings can be a powerful way to express yourself, and it’s wonderful to hear that you’re considering this approach with your partner. Taking the time to reflect and articulate your thoughts in writing might provide the clarity and connection you’re seeking.
I’m sorry to hear that you felt the need to run away from home, but I’m glad to know that spending some time alone has given you a bit of relief. This signals that perhaps your self-care can be improved. Consider starting a self-care routine so that you can fill your own well-being cup first before you pour your love and kindness into other relationships. It’s important to take these moments for yourself to calibrate yourself. 
Comparing ourselves to others is a common experience, especially when it seems like everyone around us is following a certain life path. In the past, comparing ourselves helped us push forward and do better, but now it’s an outdated strategy that does more harm than good. It’s okay to unlearn this cultural belief and shift towards a growth mindset where you seek internal validation and discern for yourself what is in your highest good or well-being.
Having the pressure to be engaged can be really hard. I imagine perhaps your parents believe that being married means you will be supported. However, it’s for you to decide on your quality of life—having the label “married” but feeling miserable because your partner hasn’t got the skills that will help the marriage thrive or choosing a different path till you feel that it is a whole body yes to spend your life together. It’s may also be helpful for you to take stock of how many communication skills and conflict-resolution skills you have. There is no time limit to learn and practice these skills. Start by focusing on improving one skill at a time and build your way up.
Let me reassure you, that there is nothing wrong with you. It’s okay to have gaps in life skills. It’s the skills that are missing and not a reflection of any limitation on you. You have infinite potential. 
With the right support, knowledge, and skills, you’ll be able to have better days ahead. I’d like to strongly encourage you to work with a therapist so that you can have a caring and supportive environment to learn these skills and make life decisions based on your well-being as a priority.
Take things one step at a time and be kind to yourself.
Warm regards,
