Remember to love yourself. Self-love is a must.
Is this course-related? Hehe. I am not sure. Are you asking for an advice on how to get over someone you wanted to spend your life with? I am so sorry that you have to go through hardships like that. You know what? There's no formula for that. You have to go through the process. Cry if you must. We have to accept the fact that people come and go. You should develop self-love more. The only person that can help you is yourself. Be independent so that if people leave you, it will not feel as devastating as it is now. Having a partner is a bonus. Work on yourself first. You are loved. Trust the process. Maybe you really have to go through this for your own betterment. Be brave, little fighter!
