Frustrated

I like to think that I am a considerate housemate: I always put my washing up in the dish washer (or at least in the sink to soak first), am the only one who deals with the recycling (often taking the non-recyclable stuff out of the recycling bag and putting it in the regular rubbish, and taking out the recyclable stuff from the regular rubbish and putting it in the recycling bag), always check the living room for stray washing up before putting the dish washer on, seem to be the only one who buys cleaning tabs for the washer (and formerly tea bags, sugar, soap, light bulbs, toilet roll), always emptying ashtrays (despite not smoking myself) and clearing away rubbish from the living room, etc etc etc. Why do I feel that I get nothing back from the other housemates?
I have been considerate again today, as I usually am on my days off. Despite getting up at around 09:00 I have waited until now to go to have a shower, as some of my housemates don't leave for work until 10:30 (Jessica usually being the last out) and I am not in any rush to get anywhere today. But despite that the shower is still being used. I really need to move. It always seems that whenever I need the shower or toilet then it is always being used by one of the other guys, or their guests. It's like Picadilly Circus in here sometimes.
I so miss living on my own, when I could have a bath when I wanted (here I can't even have a bath as the hot water tank only holds enough hot water to fill about 2 inches deep in the bath. I miss having baths!), use the kitchen when I want, watch the television when I want and what I want. I really need to know if the new owner is going to let us stay on or if I need to move immediately. Hopefully I will be able to wait until my debts are paid off (August probably now), and when I have a new job, so that I can take into consideration travelling times and routes. But, whatever and whenever I know that I do want (NEED) to move.
