My temper has been flying off recently. Any minor inconvenience just gets me so pissed off.

For example I home brew my own beer. You need co2 when you Keg your beer and it cost 25$ for a bottle today 3 days after I bought the tank it all leaked out due to a bad seal

Anyway this just pissed me off and like immediately ruined my mood and I want on a tangent for 10 mins and listed all my brewing stiff on Facebook for sale.

When I was younger like 18-20 my temper was really bad but as I'm older now 25 I've been able to remain calm but recently its just getting bad again then I let things ruin my day and even go as far to say things like " nothing ever goes right for me"      " life is pointless"     " I gave the worst luck" 

Am I the only one? What can I do to help this? 

I've been making such strides on my anxiety/ agoraphobia and it seems now my depression is taking over
