I feel the world on my shoulders. I dont care about my birthday.

My birthday is in 2 days but I feel so tired. Yes its true that Im in a long distance relationship and haven't seen my love in about 9-10 months and I miss him so much. Its true that I work alot and more than an average person. Its true that my country went through war recently and I expérienced lots of stress and fear.
And the worst thing was loss of my uncle because of gallbladder cancer in less than 3 months.
Although all of this things happened I still try to survive and be strong... but deep down Im so tired... I have decided to work alot to forget my sorrows. I dont know how long it takes for me to be normal again. All I know is that Im deeply tired.
