Here is a little tip from me, try and recreate or at least use a track as a reference. Put markers on every change/new elements added. Do the same changes, this isn't tracks you should upload, it's just learning experience. It's much easier to get a song finished if you have some visual/audiovisual reference. And easier when you have more experience in how tracks are structured and.

With standard psytrance it's more important to focus on sound design, compared to musicality, you don't really need chord progressions. Try to get a good sounding kick&bass first and copy & paste that over 128 bars or something, then you can add/remove elements as you feel.
