depressed01 you are expressing a lot of disatisfaction with your life.
Do you think that maybe, what you really want is change?
It sounds like you want the possibility of love, purpose and the drive to move on in life e.g. getting your own place?
These are all very worthwhile life goals.
Having a baby now, won't help you achieve those goals, though, it'll make them harder, please trust me on this!
Could it be helpful to recognise this as you really wanting change, and start thining about what positive things you can do to make your life more enjoyable and full?
I agree with other posters, your mental health is a priority. You say you think you have ADD. I do too! (They call it "ADHD inattentive" type, but it's the same thing) I was diagnosed in my 40s. I wish I'd known sooner. I got diagnosed by going to my GP. He told me there's a mental health service in our town,. I could have just self referred, I didn't know. So I did that, spoke to someone which was the first step to getting diagnosed (about a year later).
Can you speak to your GP?
