you're allowed to be sad. you're allowed to miss them or what you had. never apologize for your feelings/emotions. let yourself heal. but don't let it distract you from your goals in life and taking care of yourself. you're allowed to heal. but in the process please try to grow as your own person. you may miss them and it may really hurt but you now have the time to complete goals and start your new journey/chapter. take care of yourself. things won't always hurt this much.
