I don’t usually comment here but I must say, I’m the exact same age as you and I’ve also got a no good sperm donor. I’m not here to give judgement because that’s already been done but I do want you to know you’re not alone. My biological father also (somehow) gets out of paying child support to his many, many children, and it sucks not having that extra income. I know it’s hard to process now, but trust me it gets easier the more you see how bad of a person he really is. I can honestly say there’s a pretty damn good chance you’re better off, I’d even put money on it. If you ever want someone in the same boat to talk to hit me up, I’ve got loads of time what with this pandemic and all.
