you got the job, it's wonderful and given current economic situation, this proves you are qualified. When I was volunteering at one organisation i took part in interviews of ppl who wanted to join (we didn't just take anyone because the job was related to mental health). What I learned is that the interviewer sees a lot, it's very hard to fool one. They took you, it means you are not just good, you are the best of the ppl who applied Don't listen to the depression talking, it's just a little ugly liar (can i kick it so it will shut up and leave you?). You should do something really nice for yourself today, make yourself a present, you really deserve it
