It really is common - I remember being irritable too. Like sugarbear said, our emotions can be all over the place -I think mine changed every 5 minutes(!) We have to deal with challenge of staying sober on top of all the feelings we drank away for so long. Add parents to the mix..... (!)
It might help if you talk to them (at a time when you're not feeling angry) and tell them that you're feeling emotional and reactive right now, that you're doing your best, but need a little more space.
Things will get better - hang in there!!
