2 weeks ago today I (23m) finally reached out to my GP, we discussed matters relating to my anxiety condition and we decided it would be best for me to start these anti-depressants for a period of time (6-8 weeks). I looked slightly over the side effects of anti depressants but overlooked the fact that it causes sexual dysfunction. Ive been taking 25mg now for 2 weeks and tomorrow is meant to be the day I start 50mg. Ive already noticed how well these meds are working for me and understand it takes time to 'rewire' my brain - Im just genuinely really concerned of the outcome over the sexual dysfunction side effect. I have no significant other at the moment and can abstain from sex until my medication period is over. I would like to know if anyone has had the same problem in the past and if this period of time would potentially have prolonged side effects or even worse, permanent. I've started overthinking, again, and have considered stopping. I understand in some cases people's sexual dysfunction has went back to normal after the first wave of side effects, but again i'm just overthinking and thinking the worse as usual. 
Any help on this matter would be appreciated.
