Welcome to SR.
I would avoid the events that you know you will struggle at in the early days. It is perfectly acceptable to not go tomorrow. Protect your sobriety and put it first even if it feels selfish-this is a time in life when being selfish is allowed
Of course, we can't and don't need to avoid events for ever but it does get easier. Being home when you are used to drinking isn't something that can be avoided either but distraction works well for me. Being realistic though, going to parties, clubs, beach & booze BBQs, drinking events in the first few weeks is dangerous behaviour. Be kind to yourself-you have nothing to prove and don't need to test yourself. Looking after your sobriety and putting it first are all you need to focus on.
Many congrats on day 5 btw
