Is complicately sad

Today... or should i say recently... I'm not quite happy... I were feeling sad from time to time... I feel lost at some time... I just don't feel good. Missing her... And today, by what she post on FB... "Every meeting is a blessing, if it isn't then it is a lesson"... It clearly stated that I'm a lesson in her life... not even a blessing... Even though for me... she is a blessing... I feel so sad and feel very bad about it... Even though I can hide it well.... I just feel bad...
