The pain will change, hopefully become less raw with time and in distance allow perspective impossible now. For now, care for yourself, those around you and be as kind and patient as you can. This is the best life advice I have to give.
"You have to decide what your highest priorities are and have the courage - pleasantly, smilingly, nonapologetically - to say 'no' to other things. And the way to do that is by having a bigger 'yes' burning inside" - Stephen Covey
When nobody else celebrates you, learn to celebrate yourself. When nobody else compliments you, then compliment yourself. It’s not up to other people to keep you encouraged. It’s up to you. Encouragement should come from the inside.
