sludgy and wont get foamy after feedings

I have been keeping my sourdough on the counter  because i was baking with it for a while and then i took a break and i kind of neglected it for about a week and it hasnt been the same. Ive been feeding it every day, sometimes 2-3 times a day and the texture of it just isnt right. It's gloopy and it wont foam up, but i'm still seeing bubbles in the starter what should i do
