Low self-confidence

It was my first time handling a collasped dog yesterday....and...I dunno what i'm doing.

Usually when an animal collasped, i'm not the first one to notice so I'll always help out when I saw my collegues bring it to the oxygen etc. However, ytd...the owner was visiting her dog then she just suddenly turn around and tell me that her dog had stop breathing. The first thing I did was to check it's reflexes...no reflexes...I double confirm...still dont have. Hence, I check the gum...pale..double check, still pale...then I informed my collegues. That was when she told me to bring to the oxygen.
I dont know why the first thing that came into my mind was to check the reflexes and gum instead of something else like heartbeat or pulse.
Well, I've said ald...I dunno what i'm doing. =/

The dog died in the end thou.
And I cried...
Somehow, i'm disappointed with myself.
I recalled, and I wonder...did I do the right thing?
Why am I double checking everything that I was doing?
I should have bring the dog to the oxygen as soon as I see that there's no reflexes nor pale gum right?
If I did not double check, I could have save the time and bring it to the oxygen earlier?
Double-checking is not wrong. but for this instance, was it not appropriate?
Well, I tried to console myself. I'm still new. I've only work for 8 days...
Although my collegues told me that I've did my part and the dog had already being unstable all along...but still...the disappointment was there. The doubt that I had with myself was there.

I think I got low self-confidence.
Double-checking things seems to be a habit for me.
Assurance from somebody seems to be what I always need.
For most of the things I do, I'll always like to ask someone to get assurance from it despite myself knowing that I am doing was correct.

Another example would be my driving test...
I know that my car position was wrong, but I doesnt not have anyone to confirm with me that it's wrong...hence I'll think that my assumption was incorrect and hence did not make any adjustment. And I think that's why I fail my test once and again.

Damn. no one told me working can be that stressful emotionally. I thought I could handle that.
Got cheated. The period during SIP wasnt like this.
3 years of vet tech course was not enough.
More reading up requires...
LOL.
