Illegal Lockout by Landlord | subletter trashed my apartment

I've been trying to resolve this on my own but I'm stuck.

subletter trashed my apartment. I've been dealing with this for about 13 weeks now and the situation isn't improving.

I have been in this property for 8 years. My monthly rent is $3,313. I have a written lease.

Am I overthinking this or is this a real legal issue worth pursuing?

I went through almost the exact same thing.

What trips people up most is hiring an attorney to send the initial letter. I'd recommend being patient with the process instead.
