Your baby may have colic ,but I am not sure .
Best thing to do is have a chat with your midwife or Health vistor about your concerns(worries) about your baby.
A lot of first time mothers struggle or feel confused about what's the right thing to do.
It is often a case of try and error, finding out different ways, to which one will be effective work for you and your baby.
Don't struggle on your own, don't feel like a failure that you do not know everything !
Nobody is a expert bringing up a children ,especially the first time.
You sound like a good enough mum,
Make sure you get enough plenty of support .
I hope you have good family members /or members of your partner family to help you, support you?
It must be particularly isolating hard with these lockdowns going on too.
Is there any mother and baby groups networks on internet?
Have you got any friends/family members with baby's/or young children to talk to?
Such as support bubbles?
Thank god, this latest lockdown will come to end soon.
And the weather is getting better makes such a difference in how everybody feels.
These lockdowns have felt like being under house arrest /or prison at time,(well latest lockdown has felt like this.
Take care

ps I can not understand why not more people have not replied to your post thread.
As your problem is quite a common issue that new parents/first time parents experience.
