Fluoxetine - has it helped?

[TwoAndMe]

Just outside the chemist waiting to pick up a prescription of this medication. It's taken many months for to finally accept that I have to try this medication.
I have had a difficult year, haven't we all?! I'm a nurse and really struggled with work and home schooling my dc's (15 and 13). They're a little older so I have been able to leave them to it. I have had to, I'm a single parent. However, they've struggled at times and needed my help, which is absolutely fine but it's hard with work etc. I. Just exhausted. I am also managing a few physical health issues that it now appears to be stress/anxiety related. I have absolutely no motivation and feel flat most of the time. I feel so guilty as I feel irritable too. Everything just feels like too much. I know what i should be doing but struggling to do it.
I'm wondering what your experience is/was with this medication?

@jan9876 That's terrible service from Better Counselling! Can you get a refund? Talking helps for sure but it doesn't have to be a counsellor. A trusted friend perhaps? If you get desperate some mental health charities have free text/phone lines as well. It is so hard for everyone right now, we're all holding on by our fingernails. But sleep is so important so it's concerning that your sleep is so poor at present. Perhaps give it a few more days & then speak to your GP? I hope you have a good day today - just getting up & putting one foot in front of the other deserves a medal x
