how am I feeling

hi all just a vent post ect,Im feeling tired its been a busy week ,Im still on holiday go back home in a few days,talking alot and being outwardly social with family who Im staying with at the moment but also need alot of alone time,been out quite a bit for a number of nights at the momment,have started yelling at random family members,maybe yelling a bit too much at times ,last night was crying in public but hid my tears,when I dont feel ok I make out I am,other times Im very outspoken to family members about how I feel,also feel as if Ive got the feeling that Im going to miss out on having a relationship ect thats me feeling that way,its been a good time but sometimes getting tired,sometimes I dont know how I feel inside is it depression or just empty feeling as if times running out and I am missing out on things socially
