Insecure and just can't focus

I know that with OCD can come other things like depression and ADHD, etc. I know do experience depression but I have also been wondering if I experience ADHD too. It is so hard for me to focus on a task. I get so many ideas of things I want to do and I get excited about it and then I never start or I barely give it a chance and I give up. I have been like this my whole life. The only thing I feel I am semi-good at is being a mom. I am passionate about my children as most mothers are. When it comes to anything else than it just doesn't happen. I have had dreams about making candles and I actually did make them but after the kit was used then that was it. I make excuses for everything and it makes me mad. I have had dreams about selling things on ebay and making money, making other things and selling them and making money. Dreams of having  a nice garden, but something always gets in the way. I went shopping for some clothes this weekend and I always seem to come home empty handed. I can't find anything that looks good on me or it's too expensive. Then after thinking about doing these things and then finding reasons why I can't do them I get really tired and just want to crawl into a little ball and hide. I did something out of the ordinary and I signed up to take a class at the community college. It starts next week. It is just an online class but I had to take several steps to get there. I don't even trust myself at following through on things. That's not cool. I was going to post some things on ebay today and when I got home I noticed all the clothes are wrinkled and it's just going to be so much work and I probably won't even sell anything. I hate being so hard on myself and feeling like I'm not worthy of having success. I just don't know how to get over this mind set. I want to be successful and I belive I am worth it but I just don't know how to do it.

Burnout wash and antifreeze anxiety

I am a stay-at-home-mom.  I buy clothing for everyone but myself until mine is falling apart. I know it's sad but true. It doesn't really bother me. I wear basic clothing. Usually I wear jeans and some sort of black cotton shirt. I know it's boring. I don't like to stand out. I have felt like it would be nice to have a little more variety but I never have the money and until I lose the roll on my tummy then black is it. Anyway, I went to look for a few clothing items the other day and I actually bought them before deciding to put them back. I came home and washed them. I was looking at the tag on one of the shirts after I washed it and it said "burnout wash".  That struck some worry with me. I didn't know what it was so I looked it up on the internet. It's some type of wash they do to make it look worn. They use sulpheric acid. That's great. Now, I've had some issues with laundry being contaminated. I took back the shirt to the store yesterday. I know I should've just worn it but I couldn't.
The antifreeze will keep bothering me until it's out of our shed. I had my husband move it from the garage to the shed. I knew it would bother me because of the tools and lawn mower in there. I just didn't want it in the garage and I didn't want to move the lawn mower to the garage because it'll smell like gas and contaminate. Yesterday alot of people were mowing their lawns because it was the first nice day we've had in a while. I am dreading when my husband mows our lawn because of my fear that the lawn mower is now contaminated with the antifreeze fumes. Then when he comes inside he will contaminate everything he touches. I get so mad then that he bought that antifreeze. It just didn't have to be like this. I do not want chemicals near my home.
