Please Help me get my rights to see my son

In March 2017 was the best day of my life, it was the day my little boy came into my life. I loved every single second I have had with him and could not be more proud of the little boy he has become
i can not wait to see him grow into a young man.
sadly in the same year his mum and I separated and unfortunately it was not on good terms for one reason or another’s both made mistakes and we could not continue as we were.
since then everyday has been a challenge for me to see my son and it has become increasingly more difficult and has been causing unnecessary stress and upset not only to myself but to my little boy and it breaks my heart.

I really want the my time with my son to be happy and for my time to be my time and my time to be fair

i don’t want to miss anymore of my little mans life and I will not give up trying to see him and will do anything in my power to be the best dad I can be and to see him as much as I can.

unfortunately to this I will have to go to court and the problem is, I am not financially in a position for this.

I am asking for your help, please help me to have my time with my boy
anything you spare will go a long way to putting a smile on my boys and my face 
I appreciate any help you can give.
