pottery problems

Kids have been driving me crackers today, late night (for them) last night after we went out for something to eat as a special occasion, to Hobees (hmm, well, tried it once, dont need to bother going again now). Anyhow, as a result, uncooperative, grumpy children, despite a trip to the park to meet up with friends today.  By the end of the day I had had enough,(a trip to the supermarket really helped things along, always a pleasure with 3 children) so went straight off to pottery as soon as we got back from their swimming lessons (corralling a tied, mischievous 2 year old around the edge of a swimming pool = not fun).  Anyhow, I got there and first thing I did was check the glazing shelves to find the mugs I had glazed had not gone well, and a grumpy note telling me what I had done wrong, then I went into the studio and was told the same thing again, this time in front of everyone in the room - beamer.  It was a different night to the night I usually go, which makes me nervous, just a comfort zone thing I guess, with different people around I don't know so well.  Anyway, I dont mind making mistakes and non perfect stuff, I am learning after all, sometimes the teachers try and get you to correct things that I am happy to let slide some times, or I do things I don't /really/ want to do, in their eagerness to help/teach you.  This time the critique of my jar with lid left me feeling shite.  It wasn't bad, and its only my second jar with lid (first one also fell foul to my shite glazing skills).  I think on top of that, husband having a new exciting job, people around me talking about how they have picked up the guitar having not played for 10 years, and another girl being a fabulous potter, looking like Jennifer Aniston AND being a teacher as well, has left me feeling a bit pathetic.  I don't feel I have accomplished much apart from having children, who will (quite rightly) grow up and move on.  A bout of self pity, and the above people were not in anyway bragging or showing off, it was just information that occurred, but I do feel like a bit of a baby machine, with few real skills or accomplishments.  Problem is, I don't know, and never really known what I want to do. :-( :-( Ho hum.
