Serious question

Hi everyone , I have a question . Im currently at a really hard place in my life right now and have been homeless for a while now , because of this I haven’t been allowed to be in my kids life as much as I want to and it’s killing me . Well yesterday to my surprise I received a last minute invitation to my kids bday party this weekend which I’m usually not allowed to attend due to not being “ presentable “ . You can imagine how excited and filled with joy I was , for the first time in a while I was truely happy. Well all that happiness turned into worries when I started thinking about what I will wear? will I be able to get a shower in time ? Will I even be able to get gift? Will I look presentable and not embarrass my kid ? I guess I’m just overthinking it but my question is this , does anyone know any church or organization that helps homeless get clothing or hygiene supplies ? Also I know some churches do toy drives maybe someone knows where I can get a toy ? I know it’s a short notice but any advice is appreciated, I just want to look and feel like a normal person and not be looked at differently or looked down on by others I want my kid to feel good about me being there . Thanks in advance and god bless!
