As pinkfrocks says, you have to assess how much your symptoms are impacting on your quality of life.
For me, the impact was huge and I reached the point where I barely recognised myself anymore. I was so often irrationally anxious and withdrawn. Often shattered too, thanks to the insomnia.
I could longer find any 'joy' in my life. Every where I looked my life seemed bleak and hopeless. I was struggling to even engage with my children and DH. I was letting friends down and not pulling my weight at work.
I had reached the end of my tether. To be honest I would have necked neat rat piss, if someone had promised it would make me feel better. But I saw a consultant who assured me that what I needed was HRT.
I have just finished my 4th week of HRT. I wear a Estradot 25mg patch, and take separate Utrogestan on days 15-26 of my cycle.
I already feel so much better. Much more like my old self again. The quality of my sleep is good again. My life feels hopeful and brighter 
If at all possible I would advise a referral to a menopause clinic to see a specialist. GPs generally know very little about HRT.
