Serious question

Just wondering if anyone has any advice? I’m at a very low point in my life right now and have been homeless for a while and because of that I am rarely allowed in my kid’s life . To my surprise yesterday I received an invite to a birthday celebration for my kid this weekend , which I usually never get invited to due to me not being “presentable”. I was filled with happiness and joy I was ecstatic to be able to spend their special day with them . Well after I calmed down and started thinking about it all that happiness turned into worries , what would I wear , would I smell good would I not look “bummy” will people judge me , what will I bring for a present .. I just kept overthinking all night . Well my question is this I know there’s places that give clothes to people in need and I also know there’s places that do toy drives for the less fortunate, does anyone know somewhere I can get something to wear for the party maybe some where I can get a toy also ? Any advice is appreciated, thank you and god bless !
