If police had no warrant and I told them to leave.... They threatened lied and tricked me into signing a warrant?

Hello The police along with swag team aside raided a neighbor 4 doors down... I walked outside hearing ruckus... An officer approaches me n tells me not to move...when I do he yells and tries to stop me.. . I then enter my house where he follows me saying oh I can come in? Maybe saying he can come here as in my back porch to talk (I was scared and completely unaware of my rights and stupid!) but on his talkie saying my duplex number... Next thing I know cops are coming in from. The upstairs front door I accidentally left unlocked.... 6 Dea officers surrounding me... They proceed with more lies and my exact words were 'what's going on? Get out!... They then threaten I will lose my daughter and everything unless I' cooperate and sign this paper letting them search ' I said I wanted to call my lawyer... They say go ahead but won't leave... They already saw my Marijuana pipe and I knew I was going to jail regardless and idioticly sign the warrant. They go to a complete different flo
