I agree with everyone above, you are strong otherwise you would have cracked while being abused.
When someone dies they say there is a process to go through and one of these steps is anger, well in my opinion, when we let someone go or are let go we go through the same processes and one of them being angry. Two months may seem like forever while going through the pain but really, it's not a long time at all, you need more time to get through this. It will get better, promise.
stay healthy, find some healthy things to do with your spare time, and all will play itself out and be good.
