Need help I am worried.

Hello everyone
I am 21M, in 11th day Hard Mode.

4 months ago, I took TCA antidepressant for only 5 days. then stopped taking it. but it was too late. I lost everything. now I have anhedonia (feeling no emotion), pssd, terrible memory, lack of concentration.
I had genital numbness and 0 libido, thinking about sex disgusted me. now the genital numbness went away. libido improved but not as it used to be. I have morning wood sometimes. sex drive is still terrible. thinking about sex, kissing, cuddling seems pointless ( but not disgusting ) now.

before this antidepressant I used to masturbate 3+ every day. but now it has been 11 days and I don't even think about sex. it is easy to hard mode it for the rest of my life with this condition.

I did a blood work. SHBG and Total Testosterone are fine but Free Testosterone and Vitamin B12 are low. an urologist prescribed sustanon 250mg 1M injection once in 3 weeks

for 3 times which means after 9 weeks I check my hormones again.

now my questions are :

• should I do the injections ? does it have any serious side effect like cancer, permanent infertility or make my body stop producing testosterone and sperm itself ?
• if I do the injection what should I expect ? what difference it make in my nofap progress ?
• is there anyone that recovered from anhedonia and pssd with nofap ? or make it worse ?
• should I do nofap when I can watch porn without feeling pleasure ?

I have been staying positive for 4 months but sometimes my condition makes me suicidal primarily the anhedonia.

 

I think you didnt get what am asking. is it pointless for someone to do nofap with pssd ? does testosterone injections have any effect on the progress ?
