Need help.

it has been 2 months now since drunkenly slept with a transgendered person and i havent slept well since, feel like i am losing My mind. I feel like Who i was before that incident died that night. I ruined My summer, cant work out, cant Eat properly, cant tell anyone about it and cant explain to My parents why im acting differentor seem
Down. Really feel low and dont know Where togo from here....
Talking to a therapist is a option but that Will make me feel worse as that Will be yet another consequense of that night. I cant laugh genuinly cant look certain people in the eye. I litteraly spend Evert day thinking about this from the minute i Wake up to the minute i go to sleep...

 

I also just got tested and i aquired chlamydia, not sure If it was from
Unprotected oral or a girl i slept with 2 weeks prior without condom. And that is another thing that makes me feel bad that i Had a girl i could have been serious with but now i cant see myself being with any girl the way i feel.
