salah problems

salaam

I have a really bad problem when it comes to reading salah -i feel that im not saying the word properly - for example tje letter 'thoy' doesnt come out properly no matter how hard i try - so i am repeating the line over and over again up to the point where i read the whiole surat again sometimes even twice - an almost all the time i am reading the same salah 2-3 times sometimes it goes up to 5 times -

if i feel like ive just runied my salah then i rush it so i can read it again - i getting rerally stressed - i dont know what to do -

I take soo long now that it effects me - by the time im finished ready my back is hurting -the other day asr took me 40 min to read - i dont know how to get out of this phase - i say to myself before ready salah that its fine and i can do this - but as soon as i finish the first ruku i know im going to read it again -

i go to tajweed to improve my acent and reading

its weird sometimes my words come out properly and most of the time they dont - so i keep repeating my self until i know they are coming out right
