After a few days, I resigned from my job in a construction store, which I had been looking for for a long time. I was afraid of the responsibility for large orders and calculating the dimensions of the floor covering. All this and the customer service overwhelmed me. When the stress disappeared from me, I started to regret this decision. I fell into depression and I have no strength to do anything. I tried to go back but it was too late. Unfortunately I can’t find anything right now. I am an introvert and I suspect that I am highly sensitive. Is working in retail just not for me or have I made a mistake?
