Folks: Work Related Advise Needed Help!!

So, I'm a graduate from BBA and I'm working with a small to medium sized organization with around 200 people. I'm a guy. It's in Education Sector. I joined right after my graduation. The first year, I did nothing so I was given a formality hike of 5k. They offered me 20k initially p.m. Now my 2nd year working here is completed so now, I have done more than 25 major roles which no one can do. That makes up work of more than 20+ people. Now that i asked for a raise, they are saying they are in losses and they don't have the budget and shit. The only reason I'm working here is that I love the Manager aka Director. He has been like a mentor, when I was facing hardship, he has given me money without even a second thought. I have been discussing this with him. Now he was saying the organization might increase my salary to 30k. I'm like the fuck are you even speaking. I really don't wanna leave the organization because of this person at the same time I don't wanna stay in an organization which doesn't give an absolute crap about me. Please tell me what shall I do. These are the points I raised: 1. I need to get paid for the value I give. I have done more than 20+ peoples works. Even if you hire some incompetent people, the time, value and efforts would cost more than to pay me. His counter: Treat this organization as a cost-cutting and work with me on other businesses and which he offered me to compensate with if I work there My thought: if I work here, and get compensates there. What about the work do there? How will I be compensated? 2. We are ready to pay more to people who do jackshit work but we have policies to people who actually do work? They have gone over the budget for people who talked big and did absolute shit. His counter: We are in losses and we might not have the budget My thought: So we are doing cost cutting by hiring shitty people for more money and compensating it by paying the valuable people jackshit? Please help me Thanks!
