Tough

i just celebrated my daughters 7 year angelversary and it was just as hard as the first year. My youngest son kept telling me she was with him and with me for a few weeks. He hasn't mentioned it since. He would say stuff like mom she wants a hug, she loves you and on his birthday he let a balloon go and said he wanted to wait for her to get outside because she was going to go home with the balloon. I didn't know what to think until he brought home a paper from school and the question was write and draw something that comes in twos and he wrote "my angel, she has 2 wings" and drew an angel with colorful wings which my oldest a few days after her passing said he saw her and she had rainbow angel wings, my thing with her is rainbows and he was 2 when this happened so he had no idea! My mind was all over the place when my youngest started saying she was here with us. It stopped after her birthday. The other night I woke up out of no where with a strong feeling something was coming close to me from the hallway and "I love you mommy" just popped in my head. It was a weird feeling and i was embarrassed to tell anybody. Has anybody ever received signs from their angel like this??
