Beginner Gardening: meyer lemon blossoms, but no fruit! , 0 by TXBBQ

I have a Meyer Lemon that I bought from Home Depot a couple of months back. At first I tried to let it grow outside for a few days, then I became concerned when I saw ants and spiders all over the soil. I shooed them away and brought it inside, but it wasn't getting enough light and nats developed, along with little mushroom-looking things.

Now, after some thinning of non-productive branches, it's back outside mounted on bricks, but this horrible, intensely HOT Texas sun (Zone 8) seems on some days to be incinerating a few leaves. I only have five fruits. One of those is quite little, and it seems to be going bad (bottom left of pic). The others are of fairly decent size, but they don't seem to be growing any and no new fruit seems to be setting. I will appreciate all the help I can get. By the way, I bought & used Osmocote, and I used Super Thrive consistently. I have been guilty of watering too much, but I have mended my bad ways in recent days. Suggestions, ideas?
