Are you helping because you genuinely want to help, or are you helping because you’ll feel you’re “owed” something after you do? Whether that’s approval, friendship, etc? If it’s the latter, there’s a lot of baked in manipulation and dishonesty in your approach.
Focus on yourself. Help yourself. No one owes you anything and the only one responsible for you is you.
This doesn’t apply to furniture but the Goodwills in my area ship all the good stuff to a central location two counties away where it can be listed for sale online. The stuff in store is mostly garbage.
