Hello Doctor, I Haven't Been Feeling Great For A Few

Hello Doctor, I haven't been feeling great for a few months now and its got worse over the last few weeks.
I've recently been off work with stress - I haven't taken any medication for it
I suffer with stomach pain, feel sick in the morning and during the day, feel hungry but don't want to eat, hot flushes, I also get a pain in my chest and reflux.
I've been to my doctor but she just said it was reflux / back pain.
I cant remember the last time I actually felt ok.
