Assalamu-Alaykum Brother,
Before anything, congrats on having the good conscience of feeling bad about your sins, don't ever lose that.
Next thing is, you shouldn't ever ask any human being about whether Allah will forgive you for a certain sin, nor should you judge another human by saying that Allah will/will not forgive him, Allah is the most merciful judge and I'd choose Allah over anyone to be my judge on the day of judgement. No one knows better than Allah in order to give you such an answer, that is in its very nature, a matter for him (SWT).
Having said that, it is important that you do your best to repent from your sins. Trust me, it is not meant for it to be easy, otherwise everyone would've been in Jannah. We humans are supposed to make mistakes, because that's who we are. I am not "condoning sins", but they're inevitable, the same way a baby falling while trying to walk for the first time is inevitable.
And the same way motivational videos and speakers will tell you that you need to keep fighting for your entire life in order to reach your goals, you need to keep fighting your entire life to please god. God always tests us, and no one is "safe from Fitnah and sin".
There is no shame in saying that your number 1 goal is to repent from masturbation. It shouldn't necessarily be your public goal, but it is a healthy goal as any can be.
Find support forums online, the NoFap community will definitely be some help, look it up. Also surround yourself with supportive friends who you can trust and will help you through this. Having someone know your problem will make you more willing to stop doing this sin.
Also, evacuate yourself from any environment, position, website, anything that might lead you to masturbate, and don't ever say "I'll just pass by", because that's Shaytan's #1 trick.
I think the beauty in Ramadan is that it shows us that we can. We can stop smoking, we can stop committing sins, we can stay up late to pray to god.
I pray to god you make the most out of this Ramadan knocking on our doors. Please pray for me, perhaps Allah will accept your prayer and shower me with his blessings and mercy.
Assalamu-Alaykum Brother.
