Welcome to the club of DIYourselfers Lessons Learned! It's NOT that exclusive ya know. We know that our 'intentions' are well placed when we attempt a DIY job but that's about all you can say when a boo-boo is made.
Plez don't feel bad if I or others have 'jested' about you or your plights. We do it to EACH OTHER too all the time. (Wick is always on me and, well, I on him!) It's all in good fun especially if you follow our Follow-ups over time. I don't think any of us 'regulars' have ever met any one of the bunch. But, in a way, you feel like you know each other nonetheless.
Heck, stick around! The advice you just gave is excellent advice. Yes, sometimes, it just pays to have a pro do it. Have a good weekend, and you know where to find us if you need any info.
