This is not a discussion on a technical topic. The heading is what I want to achieve.

Before starting, I'd like to share a brief intro about myself.

• I've been doing leetcode for about 6 months now, before that I practised on hackerrank. On both the platforms, I've done a decent amount of questions ( ~200 on hackerrank and ~280 on leetcode). Sometimes I solve 3 questions in LC contests, current rating is 1480.
• I'm pursuing B.Tech in Computer Science from a tier-3 college and have 7.66 CGPA ( currently 8th semester ).

Why do I feel depressed, stressed and demotivated -

• 16 July 2019- I secured a Pre-Placement Offer from an MNC with 2x the average CTC within one month of the start of placements. In my college, it's a rule that once a candidate secures a placement of 6+ LPA, he's not allowed to sit for any other company with less than 2 times the current offer. So, after around 2 months of waiting for the offer letter, I heard that the company had revoked my offer. What hurt me was that I missed the opportunity to sit for other good companies, and by that time only those comapanies were visiting the college who had service bonds of 2+ years.
• 8 October 2019 - Having no offer in hand, I had to somehow get another offer because that's what we come to college for. I sat for a company that had 2.5 yrs of service bond and a CTC of half of my previous compensation. Selected again, I signed the offer letter but haven't heard from them either until now.
• 12 December 2019 - Got another opportunity with a top MNC ( performance based Full-time offer ), cleared the interview and currently doing my internship here. Owing to my good performance, I received and accepted the fulltime offer on 23 March 2020, just before the beginning of the COVID-19 crisis. Again after two weeks, the recruiter said that my fulltime offer has been revoked due to the current situation. Now, I don't have any offers in hand.

I've worked very hard throughout my college life just to secure a satisfactory place in a top tech company. Here I am with such a bad luck that even my hardwork couldn't get me anything. Sometimes I really feel low, thinking about the things that happened to me. I don't deserve this. I've started solving almost 3-4 questions on leetcode on a daily basis. Even after maintaining a good profile, I don't hear anything back when I apply for other companies.

Is there anything I can do to overcome depressing and demotivating thoughts ?
I really feel like giving up now because, I've tried to give my 100% everytime just to get disappointment in return.
