What do you mean "trying"? Who have you talked to? What did you say? What did they say?
Whether you get removed from the lease depends on what the landlord and your co-signers say about it.
The landlord isn't going to care what your problems are or who pays as long as he gets 100% of his rent on time every months.
Your co-signers aren't going to want to increase their shares of the rent by letting you loose without getting a qualified replacement for you.
And even if that happens the landlord can still hold you responsible until the lease expires and everybody leaves.
Again, what do you mean by "trying"?
