There's no state wide referral system in Indiana, but many of the local bar associations (county/city) do have such programs which may provide a limited initial consultation. Expect to not get much out of this without signing on to formal representation.
You're bound by the lease you signed. If the lease provides for holdover or renewal, you're still bound to that. The only way out is to provide the proper notice and to have everyone VACATE the premises or get the landlord consent to releasing just you. In writing, by and large, means on paper or a reasonable approximation. Texts, phone messages, etc.. are not written notice. Even if you had sent a proper written notice, it likely would have little meaning if the other lessees didn't also give notice and move.
