Listen up buddy . . so many of us have been through it all.
I nearly tossed my CPL in the bin many times. Then one day a job opened up in Africa. It was fantastic. I havent looked back.
I do sympathise with you.
I now have over 3000 hours, most on caravans. I have an ATP, and experience as an airline loadmaster. this however counts for nothing, as most companies want you to sell your soul and pitch up with 737 and 319 ratings and 500 hours on type etc etc. Amazing how cadets from airlines in Kenya get a job on a 737 with 250 hours. scary thought!
if you have money, do a rating. If you have a frozen ATP, then try Qatar airways if ur under 25 I think. Many airlines in Europe and the USA will take you with low hours. in South Africa . . .forget it. . . .you need 1500 hours plus ATPL to fly as FO on a jetstream (if you can get past the politics). but if you have 700 hours, and daddy has a dc9 that you logged 200 hours on. you can get straight onto the Embraer . . . nice!
ps try tanzania. they are usually looking for new crew and expat pilots.
