Debating to stop BF and go onto formula but have such a guilt

The guilt is killing me but so is BF

I haven't enjoyed it at all its not been easy and hasn't got any easier

Were 4 months in and indont know if its her or the BF she is never happy during the day doesn't sleep well in the day or night

With covid 19 going round I can't help feel this is good for her immune system and feel guilty if I was to stop BF

But I'm also like right I could go onto formula and she could still be like this.

I think I might try a pacifder first and go from there

Shes been up since 12 its now 3:30 am shes slept for 10 mins everhtime I lay her down she's awake she's so tired

How do u even switch to formula? Transition

Its just my mum guilt like I've given in and with covid going rojnd everyone's like oh her immune system ect ect

I would hate to go onto formula and for her to be no better and ill live to regret it
