I'm starting to get more worried now - one more month and I'm stuck with a 3 month notice period

I wish I had more energy to look for a new job. Also I assume there will be a talk with my team lead when my probation time ends and I'm not sure how honest I should be about how I feel in the job. Because as much as I WANT out, leave the company completely and do something more meaningful, chances of me actually getting another job anytime soon seem slim. And I don't want to create any tension or anything.
