What do I do for work when I'm a complete fuck up?

Fair warning, I'm in one of "those" moods. I've had quite a few jobs in the last 15 years and none of them have went well. Most supervisors I've had has said the line "this job isn't for everyone" to me. Factory work, manual labor, fast food, dishwashing, housekeeping, shelf stocker, cashiering, even worked in a psych ward. Every time I've been fired for doing a bad job. I've had friends and family members get me jobs, just for them to say i was the worst they've seen and had to apologize for recommending me. Now the last 2 friends and only family i have left won't even talk about me working with them, or try to help me find a job. What do I do to remedy this situation? I just feel like I'm too stupid to do anything.
