burnt out

needing to vent about how much i work. currently i work everyday of the week, mon-fri 7am-4pm and on the weekends 12 hour shifts. i’m a vet technician and my main job is at a shelter. on the weekends i work for a mobile vaccine clinic. at home i have three dogs. i give them everything. they have their own room and a huge basket of toys. i take them all on walks 3 times a day. i play with them and work on a lot of training. i live on my own and living on your own is so damn expensive. i work so hard to never see my pay checks. i’m over whelmed with bills. my first two dogs i got on my own. the third dog was a foster fail. constantly i feel like i am failing them. i am exhausted. i get up at 5am almost every day now just to make sure the girls are walked and taken care of before i leave. right when i get home i walk and then feed them. i wait until its bed time and walk them one last time. i am physically, mentally, and emotionally drained. the other day i had to ask my parents to help with rent, i am 21. i was very embarrassed but i was out of work for awhile because a dog bit and broke my finger. the days of missed work was not compensated which put me very behind on bills. the paychecks were half of what i usually bring in. it has truly been the biggest struggle this year.
