Volunteering is great when you really find something that works for you. Be warned though it’s additive
You meet some great people and learn so much you get lot more out than you put in.
Helping YP is great Idea, one to try a bit different is see what your local youth offending service have.
They always need Youth referral order panel members. I‘ve do it for years and love it. They often have mentorship volunteers too again I’ve done it and so rewarding.
Redcross have plenty of roles more than you may think a nice one with not too much training is befriender mostly calling round for a hour and chatting over a cuppa.
Having volunteered for years and managed them both as a volunteer and paid. You do need to carful some will take the pee. But most will welcome anyone and make you feel really valued. Find out early what they will offer you, what the support they offer and not paying expenses is a no go for me. It’s a the least anyone can do.
Your local volunteer service is good place to start they should help you find something.
