Just a request, please, please, please, use some grammar! I wasn't even reading it alowd and I ran out of breath before i'd read it all, lol.
Anyway;
There are a number of things that you can check;
1. Check the bracing height - this makes a huge difference to the bow, and should really be checked when you string the bow, and periodically throughout the shoot (no-one ever does, but you should

)
2. You should be holding the bow as you would a suitcase. This is hard to explain, but if you can, get someone to show you how they do it (obviously someone who's an experienced longbow archer).
3. You must put the tension of pulling the bow across your shoulders. This helps promotes a clean release, but, again, is difficult to explain online.
4. Check your nock fit - ie the arrow nock onto the bow string. If this varies between the arrows, this can cause problems too.
5. Longbow archers need as much, if not more coaching than other disciplines. If you can, ask a coach to watch you shoot, or ask another experienced archer.
