No, those feelings are part of a reaction to specific chemicals released by the brain during early attraction, generally referred to as NRE (new relationship energy).
It will absolutely feel like love to someone the first time they experience it really strongly, but it is a completely different set of chemicals. The ones required for 'true love' take years to develop.
The ones from NRE involve dopamine, norepinephidrine, phenylethylamine and serotonin, so they are basically amphetamines, stimulants and painkillers (the painkiller part, in particular, is responsible for it actually physically hurting during a break-up while this phase is active).
It can trigger when the brain just imagines a relationship, which is why teen girls can 'fall in love' with rock stars or whatever... they imagine a relationship and their brain starts producing the chemicals to get ready for it. And so what would have happened for you is that you thought about some good times and thought about what it would be like or something along those lines, and your brain picked up the wrong intention and just ran with it. And now you're stuck with those relationship chemicals and are going to have to go through the 'break up' phase, which sucks. A lot.
Time will help, but if you end up carrying 'hope' that something can happen in the future, you will never get over it, because your brain will use that hope to keep producing the chemicals, and not accept that it's over and that there is no longer a reason to keep dealing with them.
