I found some information on this website about the whole issue of diet exercise, lifestyle and weight gain around menopause, Dandelion which might help explain what has been mentioned in a lot of posts.
http://www.menopausematters.co.uk/weightgain.phpAlso I sympathise with having to cook on a budget. However I do agree that you would benefit from changing your diet which would really help with the weight gain issue (not the distribution though!). For example you can get other cheap forms of protein which are less fatty (sausages are very high infat) and don't put on weight such as tinned tuna, eggs and other tinned fish like sardines which are also cheap. All of these contain less fat. Beans and pulses of all kinds are good and filling too.
You will probably be getting quite a lot of sugar rushes and dips from snacking on biscuits which can't be good for your insulin levels and can lead to low blood sugar and associated irritability. I appreciate they are cheap. Plain wholewheat digestive biscuits are better than others for blood sugar and contain slower release sugars. A handful of nuts and rasins, although containing sugar and fat - will fill up that whole and provide some protein and other useful nutrients!
I don't know how much time you have and whether you work full time? If so then I can see that cooking would be tiring but otherwise perhaps try experimenting a bit - I'm sure there are lots of ideas and ways to cook on a budget on the web!
I would have thought you could buy some veg as cheaply as tinned beans for example - like carrots and celery. Stir-fries are very nutritious quick to do and based around vegetables - add an egg and some noodles ( or cheap pasta) and you have a balanced healthy meal.
Lidl and Aldi sell fruit and veg much cheaper than the big supermarkets (and some are better quality!) - but the big supers also always have reduced stuff at the end of the day.
I hope you don't mind my adding these suggestions but when you say "I might not eat or do excercise very well, but even if I had the best excercise and diet, I would still feel crap if I was not on enough of the hormones I need." it really is the other way round at menopause! No amount of hormones will make you feel better if your diet is poor and you have insuficcient exercise., but I can say you are in a bit of a vicious circle at the moment.
Why not try just one little step at a time - maybe write a list of things you need or want to change, or how you want to feel, and set yourself goals - like tomorrow I will make a healthy cheap evening meal, or walk for 10 minutes. If you need some support with this why not share with us and we can encourage you along the way?!
Hope you don;t think this is a lecture but I could sense from your posts that you are at a bit of a loss and finding it all a bit overwhelming at the moment.
It will get better and as others have said try to banish negative thoughts whenever they pop into your head - starting tomorrow!!

Edit - honeybun I've just seen you have said the same as me re the fruit and veg - didn't see your post when I pressed the button as I was typing this for ages!
