4 year old behavior issues

[llmt]

am hoping someone could help me.  I have been crying all day, because I am at my wits end.  My 4 year old for, I'd say the last 6 months or so, maybe longer, has been acting out at daycare to the point where I heard him on the phone, yesterday, in a full blown screaming match.  He was crying, hysterical, has hit, pushed, or scratched children when they get in his area or take his toys.  He has been using foul language, which he has heard from other kids or on an occasion my exH or myself, as we all slip.  He has an 8 year old brother who does pick on him and it's incessant, at times.  It always seems to be in the morning after drop-off, and before lunch or nap time.  He is on the verge of getting kicked out of daycare, and I think they haven't yet, because our family has been with them so long.  All I do is cry.  He is seeing a therapist but recently had to cut down and stop because it became too expensive, as the insurance has used up the times he can go.  I just filled out the paper for a psych evaluatation, but it will take months to get him in bc of the time frame.  I have tried time outs, taking away things, everything.  I talk to him in the morning at drop off and he seems to get it, then I get the dreaded phone call.  I am about to lose my job and I need to work being divorced.  A little back history and I know this may play a big part in it, but their dad and I are divorced, legally, living in the same house, until it's sold.  We have been living like this for 2 years due to the economy, and the fact his dad had a GF on the side.  That being said, as angry and upset as I am, I choose not to fight with him in front of the children, I just make due with little interaction, unless it's about the kids.  They are in my best interest, right now.  We sleep in separate bedrooms, and the 4 year old was sleeping with me...I have been trying to get him in his own room.  Please someone help me.  I can't lose my job over this child because I am so upset at work.  I don't know where else to turn and I feel like I am going to take a nervous breakdown over this and everything.  Can a child of 4 years old be bipolar?  I don't know where his anger is coming from or how to combat it.  Please help me!!!!

PS Children copy and learn from us.. his behavior at school is what he has learned ,I doubt it will change until his life at home changes ...

No I dont think hes bi polar or anything else other than being upset and miserable and acting out. To me it speaks volumes when you say 'he has an 8 year old brother who picks on him'incessantly' can you imagine how that feels .He is acting out because of the treatment he receives I suggest you protect him and do not allow this behavior from the older child .I think you need help with the dynamics of the house hold ,family counseling may help you.... good luck....
