I think that what the OP has expressed is a stage that many leaving JWs go through. Letting go of lifelong belief in 'THE Truth' can make one reticent and cautious about all claims of truth. It can be quite mentally peaceful for a while to let go and not worry about it - to let all the arguing go on about you and be accepting of others points of view without taking sides.
This isn't necessarily where the OP will end up. The religion does not give people the ability to develop critical thinking in evaluating knowledge. It would be counterproductive to do so as those who develop critical thinking at university apply it to the religion and see it for what it is. My advice would be to try to access information on critical thinking, and develop your ability to assess whether things are likely to be true, as well as perhaps reading a primer on evolution. Jerry Coyne is very good.
