I feel like my Life is going nowhere. Please give me advice so that I can change it?

My name is Rajesh koppisetti. I graduated from a University in the stream of B.Tech with distinction. I was consistent in my academics from my child hood. But I’m an introvert, shy person so I couldn’t able to get campus placements. My Parents are against software jobs and advised me not to join any software firm. So I prepared for TS Genco for 5 months but before exam I feel sick for 6 months because of that I couldn’t able to clear it. I felt depressed as I lost one year and did all the random stuff like writing bank exams(I went up to mains but couldn’t clear it) and other Govt jobs. I learned about JIPT (Jindal Institute of Power Technology) which gives one year power plant training and provides placement opportunities. I couldn’t get any job there as power sector is in bad state and many companies didn’t show up. Now I lost two years after B.Tech. Now I don’t know what to do with my life. I feel like I ruined my own life .I don’t have any friends now. feel like my Life is going nowhere. Please kindly give me any advice so that I could change my life .
