Firstly I am sorry you are in this situation. It truly does suck. Firstly you need to make sure you are ok mentally, this is your top priority. This was literally me in April. My husband downgraded me for a younger model and he was the main earner by quite a significant amount! I was working totally from home at the time but decided I needed a job for my sanity and for reliable income. However, I still earn 90% of my money at home and you can too. I have a child so can’t commit to anywhere near 15 hours a day. Probably more like 6-7 hours.
I earn through adult chat, Neevo, UserTesting, Roamler, be my eye, take note, prolific, populus, respondent and occasionally appen. I also sell on FB and eBay sometimes and I’m building up a portfolio on TeePublic. I also do matched betting. Buy through cash back sites, check your utility is the cheapest supplier, cancel unwanted direct debits etc too.
My advice would be explore lots of things, don’t rely on only one source of income. This forum will be a huge help I promise. It literally saved me financially when I joined and there is no way I would have been able to be so self sufficient since becoming single without it!
