Some days bring with them a challenge. Or two. Or four. Sometimes those challenges stay with us for a long time. Seek to find the good in each day and be grateful, for it is within these things that we recognize the beauty of who we are and what we have.
If someone seems to not care about hurting your feelings - you can decide to forgive them. Move on because any grudges you carry will hurt you more than them. Use that energy to plan and prepare for the life you want to live and dream of. Remember this...you will want forgiveness too one day. Don't let the little things hold you down or make you always upset.
