I'm freaking stressed

i'm kinda fully stressed right now cause, back at the end of may i started working at a daycare for free  cause they needed help, and i din't really bother me if i didn't get paied i worked for the whole month of jun before the summer holidays and the last week of july. before the summer holiday my boss tolday i was going to continue to work after the holidays. Turn  she called some days ago telling me i was just going to replace my teamates when some couldn't be here. (i'm not the only one who she ask for help when she need a replacement.)

I kinda got it bad when she told me that but i quickly forgote about it already thinking about getting a new job cause i really need money.

Today she sent me a a groupe message ask if people were free to come work cause someone wasn't there (the whole freaking month of september.) i still dind't respond cause i kinda fill bad going back there now and i have so much on my mind cause in eed to calla vet for my cat cause he need his yearly check up and vaccinations but i don't have enough money so i have to call vets of my city to ask them how much they charge up for a yearly check up but i hate making phone calls, i also have to make many pphone call to find a new therapist cause now i'm 18 and i'm an adult and my therapist only do for children so i have to find a new one. and i have still so many things to do cause i'm an adult now,  plus some kid during the summer holiday, said i was the worst adult of them all (those words made me felt so bad).

i didn't thought she would ask for help this early and i was so focused on those phone calls that when she send me this message i just felt like i couldn't come to work, buuut i need money !!!!

so i'm kind panicking and feeling overwhelmed, i'm was thinking to apply for another job to get money but i still didn't finish to make changes to my job application. and so i didn't send anything. 

I feel pretty bad cause even when its for my cat heahtl i can't make up my mind to make a phone call.

if you have any advice or just something to say feel free to put a comment, i'm not really active on my space but i'll try to check if there's any replies.
