What will help me poop?

I'm so constipated and it hurts SO bad. I feel like I have to go so I go to the bathroom and I just sit there in agony because my stomach is killing me. I took some tums but that's about the only thing I have. It's 1am so I don't want to go and make coffee and that's the only thing I can think of that will help me go. THIS HURTS SO BAD. my mom made this cheese chicken Caserole that was like incredible and I stuffed myself with it😂😂😂 lord help me
