Hey Alo
It probably comes as no surprise, the secret is... practice. Ok, you also need to now what to practice! I could advise, but you would be better getting advice from @Mahesh. He works professionally as both a singing teacher and as a singer.
Nice to hear you singing... though for assessment and training purposes it is much better if your voice was heard raw... no effects at all. I understand that for someone starting their singing journey that can be a nerve wracking thing. Just remember, we all started there. Most people still get nervous no matter their experience level. They have just learned to funnel it in a constructive way (generally). So, suck it up, record something in YouTube as unlisted and share it accordingly, or maybe get a Skype assessment? Either way, people who help you need to hear your voice "as is" to really stand a chance of helping you.
Nerves are a killer. They change how your voice behaves. Your range, your tone. So, I sing everywhere I go. At first people think, "who is tis whackadoodle" but very soon they just get used to it and you become part of the scenery. Instead of being Alo you become Alo, the singing guy" big deal. That aside, when you sing all quiet and apologetic like, it changes your range, tone, sustain etc. Make your mistakes loud and proud. That way the cringe helps you fuel your motivation to exercise and your determination not to make that sort of mistake again!
Either way, have fun bud. Singing is awesome and you might just surprise yourself.
Cheers
John
