I think your friends are to blame if your bulgarian is getting worse or stays at the same level.Both english speakers and bulgarians. You should try not to hang out with too many english speakers and then you will be forced to interact in bulgarian.
However the bulgarians like to show off how smart they are and they talk to you in english. Make them stop!

In the bulgarian post I saw a comment of some asshole who corrected the dialect in which you had written some of the words. Don't try to learn proper bulgarian, any bulgarian is good enough, so long it makes sense to the listener.

Аре че одим да гледам мачо :)

Keep it up!
