Falling Apart

I don't know how to write this, or if I should, but I'm lost. I'm falling apart. I don't know what to do. The put downs from my spouse and blame are more than I can take. He says my meds have made me this way. (I have bipolar disorder.) He thinks it's all bs. I keep questioning myself, is it me, because I'm the one with mental problems.

I locked myself in the bathroom. He stood on the other side of the door with no words of sympathy, just more criticism. I lost it and trashed the bathroom. Slumped on the floor sobbing and laying in a pile of my chaos, I saw my perfume bottle shattered everywhere. He was peeking under the door, and said I bought that for you and way to go, or something to that effect. Pain, rage, and shock of how uncaring he was filled me. I grabbed a chunk of the broken bottle and drug it up and down my arm. It's not deep enough for stitches, but it's gonna scar, and it hurts, and I feel stupid...

Note: I have a psychiatrist, and we are in marriage counseling. I am not without any help.
