Big interview Wednesday

Hi everyone, so I was just informed that I landed a job interview and I needed some advice . I am currently in a really bad place in life and I am currently fighting and doing everything I can to get myself out of homelessness. Hearing I lading this interview is like a light at the end of the tunnel for me this could be what gets me out of my current situation. Being in my situation it is hard to keep up with everyday things like hygiene and clean set of clothes . I know it’s a short notice but my question is this , are there any places or organizations that can help me get a shower and some clean interview clothes maybe a haircut and some hygiene products? I know to most people these are things they don’t really think about but it is quite nerve wrecking talking to someone or even being in the same room as people and knowing that you might not smell so good , I just want to feel like a normal person again and focus on my interview … Any info is appreciated thanks
