Sleep training 2 year old boy! Help

First off I don't want any bashing.

I'm a single mom that got out of a horrible abusive relationship when I got pregnant.

Bed sharing SAFLEY was the easiest after my emergency c section and going home to no help at all, still to this DAY.

I'm exhausted, I work full time, I go to school.

My son who is going to be two in April has been teething ( 4 teeth coming in), he sleeps with me still and these past 3 weeks he has NOT BEEN SLEEPING.

every turn I make, everytime I go and use the bathroom he wakes up and crys.

I've had it I'm tired, I need to sleep.

Cry it out method didn't fancy me. Well tonight I stuck him in his pack and play. After 20 minutes of pure SCREAMING he GOT OUT OF THE PACK N PLAY. Walked into the other room I was in and smiled and gave me a hug. Well it's 1035, he is back in my bed after another attempt to put him in the pack n play.

I'm at a loss. I'm over IT !

This mama needs her bed back and sleep.

Any advice because a crib he would just get out of. And I don't own one either . Super expensive.

Help please
