Hi, I'm 30 yrs old unmarried female. Lately, I've been experiencing fast heart beat, very high pulse rate, get angry and irritated very soon, don't feel like talking to anyone, have lost apetite but I still put on weight.. I always feel like running away to far off place or jumping from a cliff. I'm unable to sleep properly at night and body doesn't feel very energetic either.

Could it be because of some hormones or any other changes? Please advice and help!

Thanks
PJ
