It is easy to see why you are so tight, you play 16 tables at a time (assuming that is real).
So my first suggestion would be to cut that in half so you can play more hands. Don’t limp everything. Figure out what to limp (and where) and then play those hands + your raisers.
Don’t limit your raising hands to AA,KK. Many many more hands should go in there and be profitable.

That is just a start.
