Your post irks me. For God's sakes your mom only died two months ago. That is nothing. Grief takes as long as it takes. There is no time limit. You have the right to wallow and be sad and whatever. After my mom died my mom last March my T asked me when I plan to be over this. That irked me also. You are allowed to grieve as long as you want. I went to a grief group because even though I love my T and didn't feel she understood. She had her mom. I had no parents anymore. She doesn't realize it is different when you don't have any parents anymore.
I am sorry she said this to you. Whatever you feel is right. Anybody who specializes or is knowledgable in grief would tell you this.
