Please guide me

I was on bench in infosys for almost 1.5 years and just went into project for 3 months, not learned anything as that was very fast paced and complex project which was about to deliver. Situation arises and I had to switch. Somehow cracked the first interview after preparing very interview centric in a month. Next company hired me as Sde 2. I told them I have only 2 years of experience but cause of my previous salary they gave me Sde 2 designation. I was happy but worried that I have no relevant skills , how I’ll be able to handle the job. I tried to learn concepts as much as I can , I assumed I’ll get into a project with existing codebase. I’ll be able to do my task by analysing the existing codebase and in few months I’ll be able to pull off. But things went south, they pushed me in a complex project which need to developed from scratch and have very strict deadlines, here the team size is really small, currently 3 developers with no senior or TL. Currently I am the main player as they gave me sde2 designation. They expect me to deliver high quality code and deliver complex story independently within limited time. And me who struggles in writing html css. Although I have conceptual knowledge of angular and knows how things work and understanding code. But due to lack of handson and no experience i feel confidence and don’t know how to proceed. I was trying to uplift myself from a long time but now I’m really tired, I feel that I’m depressed and need consultation. I feel I am no good, I have no skills and wasted 2 years of my life doing nothing. I feel worthless and my whole personality got affected. I don’t feel interest in anything, feel no hunger, just want to close my eyes and never want to open it. I feel shameful as being from a middle class family, my parent have all I wanted. Had an education loan running, my parents was very proud of me when i got my job with a decent package after college . I feel I failed them , I feel I can’t do anything in future now, everything seems dark and no light. I feel tired , heavy headed all the time . Sometimes things to leave all the things and end myself. I want guidance , I want to be good in something, feel confident and want to work and grow. I have some saving by which I’ll be able to pay education loan emi’s for 1 year, and will be able to survive with minimum expenses for 6-8 months. I am thinking to take a break for 4-5 months and upkill myself in data science or cloud as per market trends, and then enter into IT with some confidence and relevant skills. Cause currently I have no confidence and always feel fear and depression.But i fear if I do so, career break will ruin my career, what if I may not able to get the job and end up being unemployed. I will waste my 2 years and previous experience. I really need guidance at this point of time of my life . Anyone who can guide me on how to proceed from here and what to do next. I am really looking for a hope in form of guidance, I am really confused and demotivated. My life is not making any sense. If someone can guide me at this point of time and really help me out , I’ll preach you like my god for rest of my life. Please help 🙏. Save me🙏
