Unreasonable mood swing

As i grow older , I really found some distinctive changes in my behaviour.

I become very sensitive and show my temper easily especially to my family members. My mood swing high and low and it is just out of my control. At times i was so down that i feel like i am so lonely and unwanted. I hope my family members will understand my feeling and do not blame me if i really hurt you guys unintentionally.

Please make some effort to understand me.
