If you have the qualifications, you are potentially employable. But, the question I think you are asking yourself is can you get the qualifications.
I'd suggest, if you have the money, go get a PPL and the odd rating (IMC/night probably), see how you handle it, and importantly whether you enjoy it.
Then think about buying a module of theory for the ATPL, pick something nasty like air-law. See if you can cope with that.
Then if, without hopefully having spent too much money, you enjoy the flying, didn't struggle too much with the PPL, and could cope with a chunk of ATPL study (don't expect to enjoy it or find it easy, that's too much for anybody to expect), the answer is probably yes. At that point you can carry on, or if the answer was no, change track without bankrupting yourself or going down an avenue you won't ultimately enjoy.
