I really just need someone to give me advice.

This past year (2018) ive done nothing but good things.

The past few years have been really rough for me. I dropped out at 16 and went to rehab and in between had some other things happen.

This year i went back to school ( on my own) and got my ged, graduated, got a really good job as a vet tech and have been unrealistically amazing to people and being a responsible helpful person.

But recently, im having some issues with myself.

I feel like i just cant freaking win or do anything.

I am such an angry person lately and i really hate it. I dont know how to stop.

I love my job and love my friends and my family and being around people.

But as soon as i am by myself, i get into such a negative mindset and think about all of the bad things that happen to me and get so angry and violent.

Im usually not a violent person ( seeing as if ive never fought anyone and it hurts me to kill an ant) but im not sure whats happening to me. I dont like who i am.

I dont like who im becoming. I hate how angry i get and how i cant control it once im upset. It feels like im in a game of setting up dominoes ( like how you line them up to fall)... i accidentally hit one and go to fix it and then 10 more fall from the first one. I just feel like i cant win lately. Like nothing good is going for me and i cant get out of this mindset. Do any of you guys every feel like this ? What do you do to help ? Should i be talking to someone about this ? Im 18 and i have no idea what the hell to do. My parents are definitely not the people to ask for help so idk what to do.
